Last year’s disappointing Resident Evil 6 is hoping to find new life on the PC later this month. Part of that revival comes in the form of “No Mercy,” a new multiplayer mode exclusive to the PC version. What’s even more surprising is that Valve is bringing the cast of Left 4 Dead 2 to this mode.

Capcom announced today that Resident Evil 6 players will be able to play as Coach, Ellis, Rochelle and Nick in the exclusive mode. To up the ante even more, Capcom is also bringing two enemies from Left 4 Dead 2 to this mode – the Witch and the Mini-Tank.

As part of the working relationship between Capcom and Valve, the former will be bringing enemies from Resident Evil 6 to Left 4 Dead 2. Capcom is also calling on fans to put the human cast of Resident Evil 6 into Left 4 Dead 2.

The new characters are a nice love letter to the PC fans of both Resident Evil and Left 4 Dead. The new “No Mercy” mode sounds incredibly fun as well. The only disappointment is that the PC version still won’t fix Resident Evil 6’s boring, and lackluster, singleplayer campaign.
