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 0.9

New Content
This update is intended to add some flavor to the world and make it feel a bit more lively. We’ve added several new creatures to the upper parts of the world, particularly on the surface of the far side of the planet as well as relatively shallow underground. We’ve also added some new areas to explore (and a new boss) that are related to the new creatures. You will need to generate a new world from the sandbox menu or create a new character to see much of the new content.

Here are a couple of the new creatures:

Story Content
In addition to the new creatures and related content, we added a bit of story content and changed some of the existing progression a bit. We added a new button on the Pioneer Station comm device (the device that requires the battery on the top floor) and there is a new satellite dish on top of the Pioneer station, but it seems to be missing a component…

We also changed the method of obtaining the Level 2 keycard upgrade - The upgrade device is now found in the captain’s room in the Pioneer Station barracks. This update is fairly light on the direct story content, but the next update should expand on the story and the mysteries of the planet quite a bit.

Food/Cooking Changes
We re-worked the cooking/food system quite a bit. Prior to this update only a handful of food items had buffs associated with them, but in this update we’ve added buff effects to most of the foods. All fruits, mushrooms and meats now have buffs that you can get by eating them. In previous versions, you’ve been able to cook food by using the crafting menu, but now cooking is done similar to how ore is processed. We’ve added pop-up menu when you right click the campfire, and you can both cook food and process ores in the same devices.

The campfire has just one slot for ingredients, but the brick oven and advanced smelter both have 2 slots, which allows you to combine some food items to create new recipes. For example, a Juicy Fruit will give you a heal over time and a sporepod mushroom will temporarily increase your max health. Both items will fill 1/4th of your stomach, but if you cook them together you can make a food item that will give you both buffs and still just fill 1/4th of your stomach. You can also cook a fruit with a plant fiber to make Fruit Chews, which give you longer lasting buffs that fill less of your stomach.

Other Content
Some of the new creatures can inflict a bleed status effect on you, so we added Primitive Bandages (can be made with plant fiber) and Cloth Bandages that can stop the bleeding status. In addition, you can add some medicinal herbs to the cloth bandage in order to make a Poultice Bandage that heals you.

New Cooking Recipes:

  • Glazed Mushrooms - Any mushroom + any fruit
  • Glazed Meat - Any Meat + any fruit
  • Meat with Mushrooms - Any Meat + any mushroom

  • Poultice Bandage - 1x Cloth Bandage + 1x Lovely Herb
  • Makeshift Shiv - 1x Makeshift Scrap + 1x Stick + 1x Plant Fiber
  • Makeshift Spear - 1x Makeshift Shiv + 1x Makeshift Scrap + 3x Stick + 1x Plant Fiber
  • Makeshift Blow Pipe - 3x Makeshift Scrap + 1x Wood Dowel + 2x Plant Fiber

New Projects
All of these recipes are obtained by destroying matching projects that are in the world with your wrist laser.
  • Spike Trap - 6x Makeshift Scrap, 3x Logs, 3x Bones
  • Poison Trap - 6x Makeshift Scrap, 3x Logs, 8x Bones
  • Snare Trap - 6x Makeshift Scrap, 3x Logs, 3x Bones

Recipe Changes
  • All gem upgrade recipes require 2 instead of 3 gems. We will probably eventually change this back once we have more sources for gems in the world.

New Status Effects
Most of these new status effects are currently attached to various food items.
  • Increased Jump Height
  • Light Aura - Generates light around the player
  • Increased Max Energy
  • Increased Max Health
  • Increased Melee Damage
  • Protection - Reduces damage from all sources
  • Resist bleed - reduces duration and severity of bleeding
  • Increased Strange Tablet Damage - Increases the damage of all abilities used through the Strange Tablet device
  • Reduced Strange Energy Requirement - Reduces required strange energy for Strange Tablet abilities
  • Improved Dodge - Dodge roll or backjump further than normal
  • Bleeding - Slow damage over time, which can be cured by using a bandage. Inflicted by blow darts.
  • Spore Poison & Vulnerability - Increases damage from all sources

Misc Fixes
  • Fixed some issues where certain sounds would play at full volume regardless of distance. Let us know if you notice any other sound fx that seem too loud.
  • Changed the projectile attack of the golems. Instead of throwing rocks, they now use some kind of sufficiently advanced technology to levitate materials out of the ground and fling them at players

  • Fixed some issues that would cause certain tooltips to not appear when they should.

Known Issues:
  • The world generator may get stuck while generating worlds. We think we've fixed all the cases where this can happen, but we can't be completely sure that there are no more lingering issues. If you run into this issue, definitely let us know.

This update adds quite a bit of new bits of content and changes, so let us know if you run into any issues and we'll fix them ASAP. As always, we encourage any feedback you folks have about the new content (or any old content). We love hearing from you, so don't be shy =)

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.
