PO'ed

As the disgruntled Space Marine named Ox, you're on a mission to wipe out the alien menace that killed your crewmates and left you stranded on an unknown planet. Starting off with a frying pan, you can pick up butcher knives, drills, flamethrowers, guided missiles, and other armaments throughout the game's 25 levels. Little nuances, such as Ox wiping the blood from the screen after drilling a foe, in addition to the walking butts (!) and other colorful enemies, show off the title's demented sense of humor. PO'ed's steep learning curve and platform-style level design make for a challenging adventure.
