Battletech: Gray Death Legion is an unfinished mech-based shooter developed for the Sega Mega-CD and Sega Saturn, originally planned for a January 1995 release by Absolute Entertainment, set within FASA's Battletech universe. The game features first-person gameplay and shares similarities with Absolute's earlier title, RDF: Global Conflict, also available on the Mega-CD. Little is known about the Saturn version beyond a few magazine references, but it was probably designed to play in a similar fashion. Development was halted indefinitely in late 1995 due to Absolute's financial struggles. In the 2000s, a prototype of the Mega-CD version surfaced, later seeing a commercial, unlicensed release by Good Deal Games.
