Uh.. Sorry but also a -1 If it's a normal huge firing at its normal rate, that's a lot of harpoons being sent out. All it takes is some camper to sit in a corner of the map spamming it, or any corner real and just sitting there with his mouse button down. I mean yeah they have to reload after a bit but still.. Door spamming in a closet will help that. Now, if it's any gun, shooting harpoons at like one per second or two per second, it's not much different than the normal Harpoon Round.
It would be a thrill to play, but probably a bitch to code and a bitch to the server with lag and what not.
how about a fun round where no one has a gun and a gun is hiding on the map and the first one to find and shoot it crashes the server that sounds like fun
