Arrrrrrrrrrrrrrrg, ive got some nifty ideas to rank my own(Random headquarters reassigned, shown on map by a Yellow star that changes and possibly even some graphic countdowns) <3

Pretty much as good as you can get for that event I think. also I could make a custom npc mesh to look like a headquarter <33 if I wanted to go advanced make the npc a building that I can remove/relocate and it appears you can jump inside it(Maybe a laptop inside it too). :P
#edit2
That would cause a jump on npc exception, easily bypassed by just doing a check on what map/or what npc your trying to jump on(If its in a AllowedList then let you jump on)

@Copz: I could make a PK City with little awards for being the LastManStanding in the map. But you cant die while players join it'd be like you after there 5+ players in the map if you rape them all and kill just those you get an award(LOL, Just add KillStreaks, New idea Add KillStreaks to events and shit that'd be sick(Your gonna need 50 kills to eliminate 75% of the other teams players(Just kills them) maybe some freeze streaks(Freeze other team for 5-10 seconds))))
