This game is an endless runner in which you score by collecting as many weapon crates as you can. In each weapon crate hides a random weapon. Use ridiculous weapons to fight through each stage filled with random aliens. As you collect more and more weapon crates, you also unlock more weapons to fight with.
You do not have to kill those pesky aliens but you might want to, since they are quite deadly. Also they recharge your flashlight as you deal damage to them and you surely do not want to be in the dark, right? Aliens which die in the water or by running into laser doors will respawn later with increased speed and health, so kill them quickly or collect all the crates and move on to the next stage. Also grab those crystals dropped by dead aliens to unlock additional weapons.
Hours of fun are guaranteed as you collect enough crates to reach the next milestone and unlock a new ridiculous weapon. Compare your score to other players from around the world in the leaderboard and unlock up to 11 achievements.
