How to play Super Mutant Alien Assault on Mac

"Taking up arms solo or with a friend, you must dance with death in a brutal and addictive arcade platformer shooter inspired by Super Crate Box and stuffed to the brim with unlockables. Fight through rapid fire single screen levels each with a random combination of platform layout, objective, vending machines and enemies. Dodge and weave amongst the aliens to stay alive but don’t leave them standing too long or the ship’s radiation will mutate them into bigger, nastier versions. Only by unlocking and mastering the wild variety of weapons, explosives, special abilities, defense moves and perks can you hope to survive across all three galaxies, rid your ship of the mutant menace and save the oblivious humans."
