About Signs of Danger

Raid Alien Planets for Deadly Technology

Fight through fully reactive pixel-physics alien worlds where everything burns, melts, shocks, and explodes.

Built in a custom engine up to four-player online and couch co-op, so every disaster can be shared (or play solo).

You are Convict Marines sent to unstable alien planets full of forbidden technology and dangerous relics - relics that the Imperial Empire insists do not exist. Redeem your honor by extracting with the relics - and try not to vaporize your squad too often.

Every world reacts at the pixel level. Fire spreads, liquids flow, electricity jumps, unstable chemicals explode, and exotic matter behaves unpredictably. One poorly-aimed shot can trigger a chain reaction that engulfs half the level.

Play solo or with up to three friends in seamless 4-player online and couch co-op. Expect chaos: friendly fire, fast respawns, and even faster "accidents".

Decipher the Signs of Danger

Scavenge for alien Signs. Use that forbidden tech to craft, mutate, and overload your weapons and abilities. Experiment until you create game-breaking combos that should never be allowed in the hands of any marine.

Build a shotgun that fires homing teleporting missiles. Dash through walls to liquefy enemies. Detonate a small personal nuke when you die. Release swarms of suicidal drones every time you take a hit. The right Signs will turn you into a one-person disaster zone.

But be warned: Signs behave differently depending on how they are combined with your weaponry. Careless experimentation can erase you or your entire squad. The line between godhood and catastrophe is very thin.
