I was just playing the under pass and came accross a centry gun and off cours I attacked it with my knife and on I went, In the game i was getting my ass kicked.
So i wasnt really concintrateing when the thaught of an enginering perk came to mind...
You could rob peoples centry guns from other teams and then use it on them

all very sneaky...
just annoying that you cant like turn some ones centry gun..
