What is "xybots"

Xybots is a arcade game by Atari Games. It was later ported to other platforms. In Xybots, the players must travel through a 3D maze and fight against a series of robots known as the Xybots whose mission is to destroy all mankind. The first player is "Major Rock Hardy" while the second player is "Captain Ace Gunn", but their abilities are virtually identical other than movement speed.
