Last Resort
Salmar Theatre from Zombie Panic mod
Maybe 1 or 2 other campaigns as well.
Also, I played a weekend with the Xbox360 console version on HD. I am completely spoiled on PC with the mouse and accuracy. To deal with it I tried to crank up the sensitivity on the options but it still stunk. I just auto shotty'd/AR'd my way through stuff.
One of the paddles on the controllers can be mapped to do a quick 180 degree turn and you can toggle crouch/walk. Personally, I couldn't wait to get back on PC when I came back from vacation. =P
