During the pre-round, you get a menu where you can organize all the primary and secondary weapons in order of preference, and during the fun round whenever someone gets a kill with a specific weapon, it gets locked out for everyone else for the rest of the round. If you're using a weapon when it gets locked out, you automatically get the highest weapon on your list from that category that isn't locked out. So for example, if you have a HK with your next highest priority on your list being the AK, and Xpro is on the server, you get the AK as soon as Xpro sees someone. Free-for-all deathmatch, last standing player wins.
