Super Mutant Alien Assault

"Alone or with a friend, you'll have to dance with death in this brutal and addictive arcade platformer shooter inspired by Super Crate Box and packed to the brim with unlockable content. Fight your way through fast-paced single-screen levels, each containing a random combination of platforms, targets, automata, and enemies. Dodge and dodge the aliens to stay alive, but don't leave them for too long or the ship's radiation will mutate them into even bigger, nastier versions. Only by unlocking and mastering the wild variety of weapons, explosives, special abilities, defenses, and perks can you hope to survive in all three galaxies, rid your ship of the mutant threat, and save the oblivious humans."
