This mod buffs all aim assist and bullet magnetism, so I thought I'd put together a montage of all my incredibly skillful 1v1 clips. If you're using guns that don't have bullet magnetism (like snipers or rockets) you still need to actually line up your shot with the target. Note, this is a gametype, not something I can use in Matchmaking. Also, I do not take credit for making the mod.
