Nordic Games has finally removed Games for Windows Live support from Red Faction: Guerrilla, moving the open world third-person shooter's online support over to Steamworks.
That means full Steam Support, including multiplayer and matchmaking, Steam Achievements, voice chat options and leaderboards, as well as fully migrated save games.
Nordic acquired Red Faction in the grand THQ fire sale in January 2013, and promised earlier this year they'd get rid of GFWL from Guerrilla. Executive producer Reinhard Pollice announced the news in a Steam update this week, and explained that the developers are calling this an open public beta right now. The idea is for players to test out the infrastructure for bugs and issues.
Guerrilla also uses DX9 support only now, rather than DX10 which was causing "performance drawbacks". In response to a few fans' disappointment with the removal of DX10 support, Pollice said "DX10 in Red Faction Guerrilla was just a marketing gag as there was no real advantage."
Passwords for getting in to the beta are in the community post, and there's a handy guide for gaining access right here.
