Initially released in 2009, MechWarrior: Living Legends (MWLL) is an award-winning total conversion multiplayer mod for Crysis Wars. The project became a "standalone mod" when development was transferred to its own fanbase in 2016, who incorporated a bare-bones Crysis Wars demo as part of the new install package.
MWLL uses CryEngine 2 as its engine and is set in the BattleTech universe. It is one of the few BattleTech-themed mods to have been sanctioned by Microsoft.
