Xybots is a 1987 third-person shooter arcade game by Atari Games. In Xybots, up to two players control "Major Rock Hardy" and "Captain Ace Gunn", who 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 game features a split screen display showing the gameplay on the bottom half of the screen and information on player status and the current level on the top half. Designed by Ed Logg, it was originally conceived as a sequel to his previous title, Gauntlet. The game was well received, with reviewers lauding the game's various features, particularly the cooperative multiplayer aspect. Despite this, it was met with limited financial success, which has been attributed to its unique control scheme that involves rotating the joystick to turn the player character.

Xybots was ported to various personal computers and the Atari Lynx handheld. Versions for the Nintendo Entertainment System and Sega Genesis/Mega Drive were announced, but never released. Emulated versions of the arcade game were later released as part of various compilations, starting with Midway Arcade Treasures 2 in 2004.

Gameplay

One or two players navigate through corridors as either Rock Hardy or Ace Gunn, battling enemy Xybots with a laser gun, seeking cover from enemy fire behind various objects and attempting to reach the level's exit. In certain levels, players face off against a large boss Xybot. Players move using the joystick, which also rotates to turn the player character. The lower half the screen shows the gameplay area for both players while the upper half is split between the map for the current level and the status display for each player. The display shows the player's remaining energy, which can be replenished by collecting energy pods within the levels. Energy can also be purchased at shops between levels, using coins dropped by defeated Xybots. The player can also purchase power-ups at these shops, including extra armor, increased speed, strength and firepower along with maze and enemy maps.
