also known as Nemesis

Battlefield 2142 uses hypothetical weapons and vehicles to construct a science fiction war that takes place in the 22nd century during the Ice Age, using the same game engine and similar settings as Battlefield 2. Battlefield 2142 has a much richer unlock system than its predecessor, allowing players to unlock a variety of useful weapons or props in sequence as they advance through the ranks. While retaining the 64-player Conquest mode, the game also introduces a Titan mode that supports up to 48 players simultaneously.
