F.E.A.R. 2: Project Origin Message Board  

In the demo there were certain keys you could not bind actions too, as well as mouse button 4 and 5.

This still seems to be the case for the retail version.

Kind of crappy I can't use all my mouse buttons, anyone else notice this?

Same here, I can't use Mouse4 and Mouse5 neither. And leaning disappeared too. Bad.

My guess is that its because of them porting the game to the 360 and PS3

You can use various types of mouse software to create an App-specific profile to remap your Mouse4 and Mouse5 keys to alternate keyboard keys. For example, I mapped my mouse keys to PgUp and PgDown.

If you have a Logitech mouse, the Logitech Setpoint software works fine. There are other programs you can use (try Google).

Some good soul made a program them enables 4 and 5 button mouse...can be set to be used with specific games:

FINALLY!
It took me almost 10 minutes to try and find a decent key to bind as Zoom after I switched Sprint to L.Shift...

I noticed that even if you bind "player status" to something else, Tab still opens it (thats after I rebound player status twice (to clear tab from alternate key too))

overall, this game is one of those ****ty ports..
Glad i played a friends copy before i bought it myself.

Seems like a downgrade from F.E.A.R 1
