I think a Mexican toggle switch would be better.
But I like the idea of turning PWs off. Although, I wouldn't mind if PWs were only in the map instead of also being able to use them as a kickback. But then again, no PWs at all would be nice as it'd eliminate cheap/easy kills.
How would this work? Cause just like the DLC toggle is plain stupid as it would seperate the playerpool.
I could see this working as Uncharted 2's co-op difficulty though.. but then I would also want to see it for offensive kickbacks.
