I've never seen anyone call in a Nuke that wasn't in 1st place. The good thing is everyone gets a big bonus when you get nuked. Also, if you call in a nuke, and say you're at 25-0, and the #1 guy is at 29-0, your nuke is automatically going to kill *everyone*, you technically you'll get at least 29 kills (there's always at least 4 people in FFA), so you'll either tie, or if there are 5 or more people you'll end up with 30-33 kills. Call it in at 29 kills with 8 people playing and you'll get 36 kills, so technically you'll still be in first place, most likely. People will cheat to get a Nuke on occasion though, which is gay.
