Heavy Gear is a mecha science fiction game universe published since 1994 by Canadian publisher Dream Pod 9. It includes a tabletop tactical wargame, a role-playing game, and a combat card game. The setting is also known through the PC game incarnations published by Activision in 1997 and 1999, which were developed after Activision lost the rights to the Battletech/MechWarrior series. It also spawned a 40-episode, 3D-animated TV series in 2001, which featured a much simplified version of the universe developed in the role-playing game.
