#17 works fine. i dont have time to test 15. someone mess around with it for me and see if things are working. i dont know about the other guys, but i will be looking into incorporating the M60 into the tankbuster menu. just need to figure out how and how to get it with infinate ammo and all that cool stuff. something tells me though, as i have run through once on the passing and used the gun, that its going to be a very popular gun. so that being said, i will most likely reduce its ammo size to minimize explosive ammo spray as it could easily be abused
