Zarlor Mercenary is an action game for the Atari Lynx handheld console, released by Epyx. It was a vertically scrolling shoot 'em up in which the player controlled a spacecraft destroying enemy spaceships and buildings in order to earn money which could be used to buy upgrades between levels. These upgrades included more powerful shots, side shots, regenerating shields, megabombs (damaging every enemy on the screen) and a laser which automatically targeted the nearest airborne enemy. Up to four players could play simultaneously, extra weapons being available to attack the other players.
