Please add endless mode, or a map editor mode, game is really good that it got me till morning playing.

Thanks for play Sttabers! We're working on this kind of thing.

Maybe add a game mode? 

Can you be more specific about which game mode(s) you would like to see?

maybe a customizable hoard-mode? a sort of freeplay so to speak

Can someone please help,I've recently just started playing second earth and logged back into my game today but noticed it didn't save my progress,it's not giving me the option to save it either anyone having this problem and if so how do I save my progress as don't want to be having to start from the beginning every time I start playing the game thanks

Huh. It should just be saving your campaign progress automatically. I can only guess that something went wrong during that process. If you send me your log file I can look into it. 

Can you paste your logfile here please? (pastebin.com works well for this)

Mac: ~/Library/Logs/Free Lives/Second Earth/Player.log
Windows: C:\Users\username\AppData\LocalLow\Free Lives\Second Earth\Player.log
Linux: ~/.config/unity3d/Free Lives/Second Earth/Player.log

it looks this page is dead.

But, On Discord, Developers are there.

looks they are busy for something than this game.

They are making and testing

"City building version" with more resource and factories.

But nothing major version released, since Oct.2019.

So, this Oct.2019 ver. is the game at all.

It has been longer than 6 months since you said content would be coming, whats taking you so long?

quick question why dose mission 1 crash the game when i place the garage where it wants me to

@@@@ Tips @@@@

1: it seems, it is good to Build 

a "Round About" at middle of your Base.

2:  if you have enough money, 

better build "Community Center" without Cycling road

( = skipping Tax). 

it has Zero tax, but you can boost workers quickly.

3: Build a Street far from Main Road System, 

then Spam 4+ of Garages on it and connet it to Main Road System.

After you confirmed all 4 karts launched and joined the road system, Remove the roads between Garages and the road system.

it works, Because carts don't need to go back to garages.

You can never have enough money! Glory to humanity!

How did you make this roundabout?

I can confirm number 3.

I have followed this game in the development process with great awe. I just wonder if it is in a playable state and when it will go full version? Why is this game not released on Steam or GOG? I am sure it will be well recieved and we need a competitor to They are billions!

Another question: do I have to download the game every time it is updated/patched? Or is it done automatically when I start the game?

It's still being worked on, but as far as I can tell from interactions on their Discord, work has progressed substantially from the october version.

You will need to download the game separately for every update. For now.

Very neat game. Very fleshed out for an alpha. I personally haven't encountered any problems, except maybe needing a save for long missions. I was also a little confounded about how the fertilizer stuff actually synergizes with the other buildings, so I had to experiment with that before understanding how it works. Descriptions are often overlooked by devs, and, although it's no big issue here, it could be improved a little.

One more thing that confused me a little is the waste dumps. I didn't let my hospital and oxygen scrubber fill up, so I don't know if they can get clogged up. However, once you store waste in the dump, it's there to stay. So, once you start with fertilizer, you still rely on having active waste production from buildings; you can't take waste from the dump. This seems very counter-intuitive, although I suspect it has to do with how buildings work. Either way, it's not a big thing, but maybe something worth considering.

Another example of descriptions, now that I'm thinking about it, is the hospital and oxygen scrubbers. It isn't clear to me if it requires a community center to be in its radius, or simply the houses around it. My guess is it's the former, but I'm not sure.

Good point. 

Nearest "Waste Dump Site" should have the Highest Priority for any waste-eat building, Unless Hospital got stuck for its waste.

Hospital and Ox Scrubbers can work on each house 

without Community Center. Because each house is independent objects. You can click on it.

That's good to know! So, it was down to the placement, or maybe the location of an available truck. I suppose a lot about this game is about placement, so it's not really that surprising. Thanks for the clarification.

I played the "Finally a challenge" mission yesterday, and I noticed how relatively quickly my roads would clog up with trucks, because I had so many at that point, and a lot have to go through the same choke points. It's not really a problem, except for the extremely tidy people like me. Do you have any plans to alter or add to the transportation mechanics? You solved the issue with lava transport by having the pipes bridge over roads, which is neat. Or perhaps flying cargo drones are a good (more expensive) alternative?

i am just a fan of this game.

don't have much idea.

A. You can Try to build 

a Roundabout on the mid of your base.

it is worth to try and test for Good traffic.

B. The idea flying drone is cool.

Air Port for a flying drone, 

which fly slow, hav a bit small capacity 

but don't need Road . is cool.

C. i hope Devs continue the development

and come back to this forum.

it looks No news and version up...

 since2019 Oct. i miss you developers...

Ooh haha, sorry. Either way, nice of you to reply.

I, too, would like to see a release for this game!

There's more activity on their Discord. Work has progressed a lot. Also new test builds, like this one: https://discordapp.com/channels/509693804966576188/509693949783310346/6923167306...

Thanks, installing Discord now.


it's an awesome game and I really love it.

Sometimes I pressed pause at the last second before the wave begins, then the play button disappeared that I cannot resume to normal.

It just keeps being paused and the only thing I can do is to restart the mission.

Please suggest if there is any solution to my situation.

i never see it.

try press any of ... [Space key, 2 key, 3 key.]


About Wall-Spamming.

it looks Cheaty and Un-Natural.

But, No, Don't need "Construction Time" on each building 

Because, it cost much for a programmer.

[idea] Just give the Game

{a 1 second "Global Cool Down Time" for all buildings}.

and 2 seconds for "Military" buildings. 

So you can't spamm wall.

E.g. if you build 4 length wall, 

you need to wait for 8 (2x4)  seconds

to build a next Military building.

Yay, played at final, (district 9).

idea: Before put the garage,

show the Expectated Route for the new cart.

(and show the Expectated Efficiency for the new mine).

 Latter one, would be easy to implement.

I've finished and enjoyed all the campaigns so far.

Love the art style, the gameplay and the vibe it gives.

Such a great game with so much potential.

After playing it, allow me to express some of the features I wish I could have during my play.


1. A replay of the stage after completing it would be nice, as it's almost impossible to keep an eye on each and every line of defense during the play, it would be great if I could have a replay and see how I did.

2. The use of the fertilizer is a bit underwhelming, I'm sure the buff it provides is justified, it's just I personally don't keen on going for the fertilizer build for my run. I often rather go for another community centre instead.


1. The mission tab bugged sometimes (i.e. it wouldn't complete even I've done what it told me to do). This is rare tho

2. I wish the camera angle could be more flexible

3. The vehicle's AI still have rooms to improve, or another way is to allow the player to set designated route for a particular vehicle

All in all, I love this game. I would definitely recommend anyone who's interested in base development/defense game to try out.

Looking forward for the updates!

Thanks for playing and for the feedback!

When you finish this game?


hi, discovered by chance. would like to give my feedback for now : 


1. I like the story, the way it's told, the starship troopers reminders, the capitalism satyre.

2. graphism match the theme, and the music is simple but effective, sound in general is really nicely done. (may be a little too loud when you are near the shooting)

3. The bugs are cute and sometimes i wish i could keep them as pet. They look awesome when they swarm at you 


1. Love/Hate relationship with the road system. I get all the game revolve around this concept, which is part of the love, but they are extremely tedious to manage. In an advanced future it seems a bit silly to have this one way road system too. Where are the drones for exemple ?

2. Electricity ? Why so many time you have plenty of capacitor full but all of a sudden no electricity available. It's not only weird it's irritating to see your defense line crumble because reason unknown.

3. Power pole. Could use some specific power pole, longer range but less connexion ? because as for roads, for long distance it can really be tedious. And also you can't manage the connexion and sometimes they create extra ones, i like to keep my line clear and it doesn't help.

4. The net worth value of every character is the same (the one you have on hte top right, and those of your coworkers) would be a pretty neat way to tell experience. To allow some "research" or i don't know. 

5. Lack of personnalisation. I would have loved to be able to make a bit of personnalisation/upgrading/research, idk, something than would force you to choose between more firepower or less comsumption or longer range and so on...

All in all excellent game, would give a solid 70/100 may be 80 once the alpha is over and improvement has been made. Continue the good work

Good Evening,

Finished playing through the campaign today and would give the game a solid 6 out of 10. I know the game currently sits in Alpha right now, and there is the content we can not see or access at the moment but would like to give my opinions and see how everyone else feels. 


  1. I like the story of the game, the feel of the map and the controls. I love the "Would you like to know more?" gave a flashback to Starship Troopers. 
  2. Power to humanity keeps coming up when you complete a mission, and defiantly enjoy the vibe that gives to the game. 
  3. The bugs are attractive with a variety of different warriors that you have to adjust your strategy too.  
  4. Clicking on the different NPCs in the area, you can see some different info on them and efficiently helps build a rapport with each one, it sucks when one die because a bug got through your defense. 
  5. A variety of mineral spots located throughout the map gives you a chance to expand and grow your base. Like you are building an actual settlement. 
  6. The buildings do look cool, and there is a lot of movement with some of them, like the Space Port, so they don't just sit there. The NPCs move throughout the farms and mines, so it gives the game life. 


  1. Roads-Hate this system with a passion, kind of wish it was more like Anno, you build the road to the place you need it to, and it will take care of the rest. The game takes place when technology is at its prime and way advance this us, but still, need one-way roads and trucks? 
  2. Resources-Currently only shows minerals for defense and money for civic buildings. I would like to see Food import vs. export type of thing, so I make sure to build enough farms to maintain my current population or need to develop more to expand. 
  3. Power Line Poles- Going back to the roads, feels like this could be cleaner and more organized than what is current, I hate seeing a bunch of wires hanging around, can they go underneath? 
  4. Electricity- There are several ways to produce electricity, but some lake the finesse of an advance civilization. I think the Bio Reactor goes through too much food way to fast; and not one for magma, we have super death ray, but no Magma Reactor? 
  5. Resources Not Consistent-My cash kept jumping around, and I could not figure out why my guys were fed and had enough food but kept jumping around from 250-175-189-200, the same with the minerals. 
  6. Defense structures where cool, I wished the garrison did more, and the people in it were not just regular civilians with their little pistols. Can we recruit some security or military guys to give it a little more of a punch? 
  7. Action-Did feel like a Tower Defense game for a lot of the fighting in the game, think it would be awesome if the creatures did spawn in random different spots, it would force you to make sure your guys were properly defended or maybe actively scanning for their locations. 
  8. Replayability- I like the feel of the game, and where it is going, I love games that I can build what I want and where I want, the freedom is incredible, and the space-age theme this provides is fantastic. Currently, I don't how you could replay the game, though, or how long the current standing would stay fun. Multiplayer would be fun, some corporation vs. corporation, but would need some powerful, aggressive weaponry; maybe a sonar device to lure more creatures to a guys base or security teams to sabotage. The same for single player, building a base and waiting for the spawns of monsters is fun, for about a campaign's worth.  

Anyway, that's just my opinion, again I realize this is Alpha right now, and do like the way the game is going. I appreciate the opportunity to play it and enjoyed what I have got the experience. 

Thank you. 

it looks like a fantastic game i would loooove to play it but im new to linux and im trying install it but it looks like im too noob for this .. is there a step by step guide to install this awsome game plz :( ((i use parrot os currently .. F*** windows10))

Don't know anything about Linux myself. From what I can tell you need to extract the zip and execute the .x86_64 file.

@blackzack You could try installing wine over the top of parrot.
Ave not used linux for a while but wine installs over most linux flavours.

I have downloaded the game and when I start the first mission, I get stuck on the loading screen.

Sorry about this bug!

Can you paste your logfile here please so I can have a look at it? (pastebin.com works well for this)

Hi Robbie, love the game! I also have the problem with there not being a continue campaign button at the main menu, any fix for this?

Sorry about that! Definitely a bug with the save file!

Title: Evvo save

I had a look at this but can't see anything obviously wrong :(

+77 power generation, turrets connected, turrets not able to sustain themselves. I'd like to see or know why this is like this, or what "power generation" actually means.

The more power surplus you have - the faster turrets will charge. In your case, it sounds like +77 isn't enough. Also, remember you can store extra power in capacitors between waves.

The capacitors seem to provide instant power recharge for your turrets, basically just an extension of the turrets own battery charge.  You can't rely on your power generators to get you through a wave, need to have the power stored up ahead of time.


i just created an account to say "wow". i have seen this https://img.itch.zone/aW1hZ2UvMzY3NTA5LzI1MzgxMDEuanBn/original/7igY9i.jpg and i am blown away by the use of Unity Engine if i am not mistaken, and the level of polish and complexity you are doing! amazing. as a software engineer myself i totally get the hard work this needs to be done but also the excitement when something new (feature etc) is ready. I dont know much about how many people are behind this, it look slike more than 1 man army i would say and thats even more crazy. i hope you manage to release this at some point before corona virus kills us all :P but evne if you cant, just your existing work make it into a Tycoon Engine and sell it on Unity Asset store and you will get a LOT of money out of this for sure!

There is still no update on Second Earth, what can we expect in the future and how long will it be until we see new content?


No ETA at the moment.  We're still working on it full time and have been experimenting with some fairly large scale gameplay changes.


Just a word of advice, as a subscriber of your very good product: You should consider seriously advertising your upcoming content so your current subscribers don't give up on waiting for you to finish introducing new gameplay content.
It should also serve as advertisement for more people to try Second Earth while waiting for it to be finished.

Dont know what "enemy not our enemy" on end mission

Deleted 164 days ago

You can rotate the buildings (when constructing).

Advice: criticize the game once you have learned all the features and functions.

Adept Gaming Absolutely. Anybody know first time to play new things need to pass the tutorial. Or, reject it with pro but need read the control button to basic knowledge. 


Let do it, what can do noob xXThePictureOneXx

This is explained in the first tutorial level, but I guess it wasn't clear enough. Sorry about that.

If anyone else reads this and is wondering: You press tab to rotate buildings (or click and drag left mouse)

Have a oldish laptop with windows 7, when launching it crashes... any ideas on how to make it work? What are the system requirements? I really like this kind of games...

Guys, how do I load a campaign I already started?

I played 3 missions, and when I open the game again I only have New Campaign to chose.

That sounds like a bug! The Continue Campaign button should be there :(

ok, and should I do what? download again, and unzip?

There needs to be a way to disable mortars or magma beams.  Often my mortars will empty large amounts of their preciously rare ammo on one stupid alien since they have no idea how to lead their shot.  Even if they are hitting 2 or 3 it is not worth it.  I'd love to have a way to control when they fire so as not to waste materials in between waves.

You can try stagger them so they don't all fire at once. You can also have a forward gun turret or two do deal with the trickles before they get in range of the mortars.


Hey, I found a weird glitch or legacy command or something that broke Campaign mode. I completed my third mission and wanted to give the area a custom name, but when I pressed Shift+U, the screen faded out and acted like I just completed what I guess is the last level, with a score of zero for everything. After naming that region, the map was all unlocked with the other areas called "unamed" [sic]

I guess it's not the worst thing that could have happened, but it's kinda annoying that I'll have to start the campaign from scratch if I want to finish it legitimately.

Also, how long till Sandbox mode is available?


This is a known bug that has been fixed. Shift + U is the cheat shortcut to unlock all the levels. I didn't realise it would also trigger when naming territories :O

Sorry about that!

Working on some big gameplay changes - so no eta on a new version just yet. Working on it full time though!

(1 edit)

My capacitors appear to do nothing.  Super frustrating.  I'm only on the 4th mission and getting my arse handed to me.

This really stands up above the rest. Seriously good job.

Really nice.

Robbie Fraser Awesome game!!!!!! Gj guys, really, I finish the game like 5-6 times already. Plsssssssssssss add the free mode, with unlimited waves(you can use simple logic, for example - aliens will appear every 5 minutes, first wave will be - 30 tier1, 5 tier2, 2 tier3, 0 tier4, and then every 5 mins +10%).

for the first iteration, you can add this mode with static map, or a choice of 2-3 maps (from existing levels).

This already exists in the codebase. Next update will have endless mode, but it might be a while!

Awesome game! As I described it to a friend: A little bit of Anno, a little bit of Factorio, a little bit of Tower Defense, a little bit of Surviving Mars, mixed in with a healthy dose of Starship Troopers.

Graphics are smooth and easy to look at, runs great on Linux Mint 19.1 with an Nvidia GTX 980.

Keep up the good work! Looking forward to future developments.

Hello again Robbie Fraser.

I would like to suggest to you and development - if any others work on second life with you: You should consider recording development sessions for the alpha community who are invested in second earth so we all know how things are coming along, it would also give you a chance to receive feedback on primary development. :)

Hi there! Last year we we're doing streams and some short update videos on our twitter. Maybe we should start with those again soon...


Looks good, but why on earth don't roads auto-connect and auto-rotate on corners? Couldn't figure out how to build roads so stopped playing for now.


Drag the mouse over the end of the existing road. They don't auto-connect because you sometimes want two roads next to each other that aren't connected.


I will try again later today, but honestly, it's confusing. You probably don't want to explain this to every new user :-)

The default should be auto-connect, and then for the edge case you explain how to avoid it.

I found it very intuitive to be honest, maybe some visual highlight is missing when dragging and dropping with the road tool.

I'm impressed! For a prototype, it works incredibly well so far. I have yet to encounter a real bug! It only crashed once when I was changing the resolution.

I really like the love to detail in the story/worldbuilding! Like how your different bosses insult and demean each other... Jeofry :)

How everything is hypercapitalistic and run by companies...  birthcompany?!?! What the heck!

How ones worth is simply their net worth, and so on... Well done!

The game is interesting and demanding aswell.

Thanks foor letting me play for free!


Thanks lucylu! We've recently hired a writer to help out on the story front - we have some pretty grand plans for the story/worldbuilding!

Nice one! Good luck and  have fun!

I'm i missing some the game keeps telling me to build more capacitors,  but there isn't any in the build icon/resource area.  Please help

Definitely seems like a bug. Is this at the beginning of the first level


Okay I suspect it's just you building a bunch of things the tutorial wasn't expecting and it not knowing what to do. You'll unlock capacitors later on.

Hi there, I came across your game from a YouTube video. I have always love these strategy-based, building, colonisation themed games since the early 2000s. I am downloading it now and definitely will give it a spin and share some of my thoughts. ;)

Hi team.

I played many games and think your product so cool to play.That the future game and how long are you release it? 

I have some suggesstion, are you can add the edittor mode to game to free ideas. User can build and share the map with others.

Add more model like as wind turbin and expansion the map. Degree the effect to keep game smoothly.

Thanks for the kind words! We're still working on the game, but we don't have a release date planned.

A map editor will come eventually.
