About the 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.

Story

Sensing that an apocalyptic war was imminent, the United Nations executed a last-ditch plan to save what they could of the human race. Two spacecrafts 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 14 light-years away. The Hermes reached the planet first in order to establish a presence in anticipation of the arrival of the Hephaestus.

Four 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.

Probably.
