Thats a serious Bug!
It shouldnt happen that co-operating mates turn rogue (all of them) if I hurt them a little with the outer ring of my grenades explosion.
Even If I throw molotov cocktails and they run into the fire after it burns there they get mad at me!
Whats up with that?
Isnt it easy to do a more realistic behavior for stuff like this?
I repeadedly offered my help in any ways reasonable for this when writing with the developer via E-Mail, because I have lots of practical C#, XNA and even Software Architecture knowledge.
Seems as if he takes this "I did this myself" really seriously ^^
But yeah, adding man-power to a late project, makes it even later I guess...
