Command & Conquer: Sole Survivor was a multiplayer spinoff of the original Command & Conquer game. It featured a deathmatch-style game in which each player controls a unit of the original Command & Conquer game and travels around the game arena collecting crates to increase this unit's firepower, armor, speed, attack range and reloading speed. Sole Survivor was often compared to a first-person shooter, however played with a top-down perspective of the arena. It featured no single-player mode and the multiplayer had no hints of a storyline, and was omitted from inclusion in the Command & Conquer: The First Decade compilation pack.
