If people wanna test local coop, here you go: http://www.tzarsectus.com/tools/modmanager.rar

I included the feature as part of Fluffy Manager (mod manager and trainer for various RE games). How to enable coop: change current game to Revelations 2 in the menu, launch Revelations 2, and then turn on local coop (have to activate trainer first), and then choose a chapter in the game or restart checkpoint, and that should do the trick.

There's a couple of known issues:
- Keyboard controls affect both players (I doubt I can fix this).
- Raid mode local coop doesn't work (hopefully I can get that working).
- If you turn coop on/off while you're switching between Claire/Moira in singleplayer mode, the game might get really confused. Toggling coop on and off works best while the game is paused.

The erroneous feature description was a careless oversight on our part due to the shared game description text used across a number of platforms. There's no other way to look at it; we clearly dropped the ball here and didn't handle the situation correctly.

Rest assured that our teams have been looking at a potential solution and/or options. Our plan is to make things right for the PC community, but we wanted to make sure a strong action plan is in place before sharing a more concise, official response through the Steam community.

I expect to have more info before we hit the weekend land. Please stay tuned."

That sounds like they'll consider adding local coop in a patch. I'd almost expect them to since it would be really easy for them to do so.
