Mechwarrior: Living Legends is a fan-created multiplayer mod, based in the Battletech universe, and using CryEngine 2 as its engine. It is one of the few mods to have been sanctioned by Microsoft. On December the 26th, an open beta was released via BitTorrent.
Mechwarrior: Living Legends is based in the Battletech universe and began as a mod for Quake Wars. However, for a number of reasons, the team decided to switch to Crysis and continue development on the CryEngine 2. Not long after the switch, German Crysis developer Crytek announced that the team would be one of only four to receive the Crysis Software Development Kit (SDK) in advance. The mod team has said that the final version of Mechwarrior: Living Legends will support Crysis Warhead.
