An early game from Beamer, Park Invaders puts you in the shoes of Cartman, who must make his way through several areas, armed with nothing but rocks. Using these rocks, you must through them upwards at the aliens who are shooting down on him, clearing the area of UFOs before progressing to the next area. Space Invaders parodies are nothing new to South Park Gaming, as we know, though Park Invaders gives it a slightly more platform-based twist. A very basic, repetitive game that won't last you very long.
