What the developers have to say:

Why Early Access?

“We wanted to get our game in the hands of as many people as possible, as soon as possible. We are a tiny team with no budget, so Early Access will allow us to think longer-term, and ultimately deliver a better game.”

Approximately how long will this game be in Early Access?

“Until we finish the content we have planned for the 1.0 release. We can't give you an ETA at this point, as we're still quite far from being finished.”

How is the full version planned to differ from the Early Access version?

“The full version will have more content, a complete, satisfying narrative and less bugs. What we have in the current Early Access build is a solid foundation, but now our job is to expand on that content in order to finish the game.”

What is the current state of the Early Access version?

“The current Early Access version of Signs of Life is very playable and stable. What we have now is a solid experience, although it has only a portion of the planned total content.”

Will the game be priced differently during and after Early Access?

“We have no plans to change the price between now and release.”

How are you planning on involving the Community in your development process?

“In any way we can. We're active on the Steam forums, and we love getting feedback from the community. The more you guys get involved and tell us what we're doing wrong the better the game is sure to get. We take criticism well, so don't be shy =)”

Signs of Life Update 0.5 - Multiplayer!

Got a new update for you folks. The big feature of this update is the long-requested online co-op multiplayer, today is truly a red letter day. Multiplayer uses Steamworks and is drop-in, drop-out, so you should be able to join your friends games through the friends list or the new multiplayer menu from the main menu. Right now the multiplayer is exclusively peer to peer, but we'll be looking into the option of dedicated servers before too long. We've done quite a bit of testing and things seem to be working pretty well, but multiplayer is a very complicated feature so definitely let us know if/when you run into issues.

We've decided to bump the version number to 0.5, because in a way we feel like the addition of multiplayer brings Signs of Life to about the halfway point. Almost all of our technical challenges are solved, and we'll be able to focus on mostly content and bugfixes from now on.

  • Added drop-in, drop-out multiplayer. Enabled by default, so you should be able to drop right into your friends' games.
  • Players join in the middle of the surface of the planet
  • Players show up as a blue dot on your minimap and also show up on the GPS device
  • Added a multiplayer join menu to the main menu which shows your friends that are currently playing, you can also join through the friends list
  • Added an in-game multiplayer menu that allows you to disable/enable multiplayer as well as turn on/off auto join (by default it asks for permission when a friend tries to join your game)
  • Added a player listing to the top right of the screen when the inventory menu is open and you have other players on your server
  • Added server-wide chat, opened by pressing T while in game.

Signs of Life Update 0.47

Heya folks, got another update for you, sorry for the long delay since the last update but it took us awhile to work most of the kinks out of the new tree system but it also gave us time to add a bunch of fun new stuff.

We totally re-did the tree system, which unfortunately means your trees and bushes will be wiped from existing maps and you'll probably see some fruits floating in the air where the trees/bushes used to be. You may need to use the sandbox menu to generate another map, grab some fruits, and then eat them to get the seeds to begin repopulating your pre-patch worlds with trees. On the plus side, the new trees look and work a lot better, and more details about the system are below in the notes.

We changed a lot of the behind the scenes stuff related to saving items, creatures, projects and bushes, so definitely let us know if you notice any weirdness with things not being saved correctly.

Let us know if you notice any major performance changes, the new way we're saving items may cause some lag and if so we have some ways to speed it up but we're not sure if it will cause a problem yet.

Most of the new content this update was a direct result of the feedback we've been getting from players, so we want to everyone out there for their suggestions and criticisms =) If you run into any issues, let us know in the comments, the forums or you can email us directly at

    • Fruit now grows slower, but also grows while you are away
    • Trees re-grow limbs as long as you don't cut it down to a stump.
    • In order to remove a tree, you must destroy the stump with an axe.
    • You cannot break the blocks under a tree.

  • Fixed an issue that would prevent you from splitting items in containers in the world
  • Fixed the AGIS button the HUD
  • The players fists are now "unequipped" when you die

About This Game

Signs of Life is a sci-fi survival sandbox platformer with a combination of procedurally generated and hand-crafted content. You'll explore mysterious locations, Mine blocks for resources, and meet strange (and some familiar) creatures, some of which don't even want to kill you and eat your corpse. Along the way, you'll be able to craft armor, weapons, gadgets and more to assist you in surviving in an inhospitable environment.


Sensing that an apocalyptic war was imminent, the United Nations executed a last ditch plan to save what they could of the human race. 2 crafts were launched, a massive colony ship called the Hephaestus and a smaller, faster scout ship called the Hermes. The destination was a recently discovered earth-like planet with the potential to harbor life located roughly 18 light years away. The Hermes reached the planet first in order to establish a presence in anticipation of the arrival of the Hephaestus.

4 years later, as the Hephaestus approached its destination a faint signal was detected from a nearby asteroid. Against their better judgement, the crew of the Hephaestus decided to investigate, and in doing so set in motion a chain of events that would ultimately lead to their destruction.

The good news is, you managed to survive by hitching a ride on a small escape pod just in the nick of time. The bad news is, everyone you knew and loved is dead, you have nothing but the clothes on your back, a standard issue multi-function wrist laser and a faulty artificial intelligence companion named AGIS. Oh, and the human race is probably doomed.



  • An expansive world with procedurally generated and hand-crafted content.
  • Online Co-Op Multiplayer
  • A bunch of weird alien creatures.
  • Some familiar creatures.
  • Chickens.
  • Mining, hunting, gathering.
  • Gobs of ores, materials and animal organs you can use to...
  • Craft all kinds of weapons, armor, gadgets, furniture, etc.
  • A bit of story and lore to hold the whole thing together.
  • Eggs.
  • All spiritual content in this game has been assessed by Dr. Halamkah, advisor to the stars.

Current State of Development

Signs of Life is currently in Alpha. We feel like we've put together a fun, satisfying experience that will allow us to get wider feedback while we complete the rest of the game.

Right now our first priority is making sure that the content we have in-game is as bug-free, balanced, polished and fun as possible based on feedback from you folks. We have a significant prologue/tutorial planned, as well as significant content beyond what is currently playable, so the sooner you get involved the more of an effect you'll have on the final game. We deal in hard science, and in working very closely with our personal science advisor at Sweet Dog Studios, that tends to lead to results.

We are still very much in development, and we would like you to join us in shaping the game from here on out. Your feedback is vital to us, so don't be shy =)


  • Some sound effects are missing, but we are actively working on filling them in.

I recommend this game, but really, I would wait till farther down the road. You run out of things to do extremely fast. It will be a great game when it is finished. Just not enough content for the price at the moment.

Early Access Review
Decent Terraria-type sandbox game. Leans more towards a realistic feel than the other games in the genre. Has a goofy sense of humor, but doesn't feel like it's overdone. Developer has stated they are focusing more on an enriching story than a free-form building game. Already has some interesting plot elements, but still feels a little shallow right now. Lots of construction options, but a lot of them feel kinda pointless at the current time - feels like a work in progress, which is only a bad thing if the developer doesn't follow through.

Overall at this point in time, a good game for maybe 10-15 hours of playing. I think it's worth the current asking price of $11. Looking forward to some future updates. especially the continuation of the story, and I'll probably come back and check them out.

Early Access Review
I like this game
It has a good mix of ores and weapons and armor but maybe needs an extra ore or two.
Its combat system works well and i love the fact that there is different facilitys for you to explore.
And you do run out of thengs to do but im sure they will fix that. I like the idea of still having human animals but it needs mre life and more mini bosses like the robot chicken. And im confused about the story line, Are you trying to survive or get off the planet?, Weapons are good but maybe could do with a few more. But if you like sci fi side scrollers this is for you.
I reccomend this game for all and i enjoy to this day and good luck with future development and updates developer.
