Robo Army Neo Geo SNK Arcade Cartridge  
There is no character selection in Robo Army: Player 1 controls Maxima and Player 2 controls Rocky. Both cyborgs must cross six levels before reaching the end boss. During these levels, they will face the Professor's henchmen, as well as a sub-boss and a boss in each stage. The two heroes can of course fight with their fists and feet, but they can also defend themselves by collecting improvised weapons (car carcass, barrel, destroyed robot arm).
