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