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 0.6

This update had two objectives, we wanted to make the underground a bit more interesting and we wanted to do some work on general user friendliness features. We've still got a lot of work on our plate before we'll feel like the underground is as interesting as we want it to be, but this should take us a significant step closer. We also added some sweet weapons and gadgets because they're fun to make =D We've fixed all the bugs we're aware of, but I'm sure there are some things we missed, so let us know when you run into issues. We still have a bit more planned for the new Biome, but we didn't want to keep you folks waiting any longer, so expect some new things to trickle in over the next couple weeks.

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.

Early Access Review
This is mostly a cut/paste from a feedback post I made on the discussion boards. Feel it has enough merit to share as a review. Hope you find this helpful:

-Graphics: 10/10
-Audio: 10/10
-AGIS: Epic. (Your trollish landing pod A.I. that is hell bent on shaming you into accepting responsiblity for everything that isn't your fault. He/it is mostly helpful, but offers a great distraction to early game failures. Such as when you get murdered by space goats like a newb.)

-Game Content: So WOW. Much YES. I watched the trailer, looked through the pictures. Hit up the youtubes for a few and still all of that didn't prepare me for the amount of fun and excitment to be had. I'm writing this, and then goiing back to playing I'm having so much damn fun. The ability to transfer my character between worlds is an amazing feature I've enjoyed in other titles, and I am very thankful to have it here too! (Replayability! 10/10)

-UI: Responsive and extremly user friendly. Buttons do what you'd expect them to do. There are also some you didn't think you would need, but are thankful to have! (+10 for being able to move every window!)

-Crafting System: Feels mostly balanced thus far and very easy to use.
The right click to change to a sub crafted item makes this system flawless. No digging for a thing to craft a thing. Just click and AGIS is your uncle you have a new shiney. Little to no tab swapping for detailed crafts. Carry (most of) your crafting stations with you!? (Thats right, smelt ore while slaying aliens in the same mine shaft to craft more ammo to slay more aliens.) Perfect. 10/10

-Inventory Management 100/10. (My inventory OCD is blown away by the work invested to keep my gear/mats/junk orginized and readily available. Bags, boxes, crates, furnature galore. Great work on this system!!!) (!!!!!)

-Progression/pace: After playing titles that have similar systems I started with some understanding of how progressing would no doubt work. I wasn't wrong. Very fluid transition between armor sets. Almost never felt like I was grinding for anything. Just exploring for the underground stations passively gave me the materiels I needed for each upgrade to armor/tools/crafting stations. All while ENJOYING the game. Well done.

The weapon progression did seem to be a bit lacking, but thats only because I refused to waste early mats on ammo and I thought the Leaf Sword was too damn cool looking to replace. Once Steel became an abundant item in my bags, the OP cave clearing began!
(And then I built a Material Printer and learned how to farm for Power Cores. I own my planet now. All aliens have been served eviction notices and I am currently selling mining rights to intersted buyers/fellow crash landers. Alien slave labor packages available to serious investors.)

Tons more to be experienced in this title that I haven't mentioned. Exploring and discovering those features will leave you feeling rewarded and 100% satisfied with your purchase even as an Early Access game. This belongs in your library.

Early Access Review
Alright, at the start, really wasn't fond of this game. Felt it was underdeveloped and extremely annoying. Really just thought it was some cheap game trying to make a cheap buck. To be honest, not a great game...yet. The developer(s) seems to really actually care about their and work with the community. I mean, bloody hell, I wrote an angry and rude review yet they actually spoke to me and spoke calmly. The game may not be at it's peak yet, but the developers are working hard to make it something desirable and really step up and communicate with their community. (Hey, maybe they won't have a set play style for a long time then drastically change it like Starbound has...TWICE! tbh these guys would probably ask before butchering an entire play style. gg)

Early Access Review
What is it?
Signs of Life is a sci fi Metroidvania sandbox game that involves lots of digging and collecting resources in order to craft better items.

How are the devs?
The developers do read the forums and often comment on feedback and questions.

How much content is there right now?
There's actually a pretty good amount of content for an Early Access game. I was able to complete the amount of story there is right now and get to the high tier items in about 20ish hours.

Is there multiplayer?
Yes. I haven't gotten a chance to test it out yet but it was added recently.

Are there Steam trading cards and emoticons?
There sure are.

Is it worth the cost?
I suppose it depends on what you think of Early Access games. If you're okay with purchasing the game and playing it with the possibility of encountering bugs and before all of the content is added, its a fine purchase imo. If you don't like that idea, maybe you should just hold on while it develops a bit more.
