You can now have two players on PC but there are some bugs.
Following backlash from fans upon the discovery that Resident Evil: Revelations 2 on PC didn’t support offline co-op (with clarifications only issued on the day of release), Capcom has now added split-screen co-op to the game on Steam. The feature is in the beta stage as of now and if you have two controllers that support XInput, you can give it a shot. Local-co-op support is available in both the campaign and Raid mode.
The interface hasn’t been changed to accommodate co-op support but you should be able to access it. In campaign mode, simply hit the Start button on the second controller during gameplay. In Raid mode, press the Start button in the starting area. If you exit campaign or Raid mode, the game will automatically return to a single-player set-up.
