Valve loves collaborating with third-party partners whenever they come a-knocking. Capcom has announced that the upcoming PC version of Resident Evil 6 will have cross-over features with Left 4 Dead 2. Best of all, the cross-over features will be free for players of either game to access and play.
New to the PC version of Resident Evil 6 is an exclusive mode: "The Mercenaries No Mercy." In this mode, players will be able to play as one of the four survivors of Left 4 Dead 2: Coach, Nick, Ellis, and Rochelle. Not only will players fight against Capcom's horde of undead, but the Witch and Mini Tank will make special "cameo appearances" where they try to kill you. This mode will be available for all PC owners of Resident Evil 6 on April 5th.
Conversely, the PC version of Left 4 Dead 2 will feature new enemies taken from the Resident Evil universe. The Lepotitsa, Napad, and Ogroman will appear in Valve's game "this spring."
Valve's Chet Faliszek said that "we're huge Resident Evil fans, so when the opportunity arose to work directly with Capcom to combine L4D2 and RE6, we jumped at it." Also, this promo is also much, much cooler than Team Fortress 2 hats, we'd argue.
