Ok, here's my shot at a VIP variant:
In this scenario I'm going to say there are 20 people (since that's a easily obtainable number). Team 1, otherwise known as the death squad, has the majority of the players, lets say 15. Team 2, otherwise known as the Templar (because I like that word) have 4 members, and the last slot is reserved for the VIP. In this scenario the Templar have to retrieve the VIP from an undisclosed spawn point (decided by an admin after the game starts) and start to take that person from point to point retrieving relics or items of some sort.
Rules:
The death squad have no re-spawns, that's right I said 0 re-spawns.
The Templar cannot re-spawn, instead they have to have the VIP use one of the relics he/she retrieves to grant life to the downed Templar.
The VIP can only carry a pistol or shotgun
How to win:
Death squad: Eliminate the VIP (who cares how many Templar's you kill when they can be brought back?)
Templar: Gather all relics or kill all the head hunters.
I know its pretty basic but the planning that the death squad has to use to prevent their numbers from being thinned out due to no re-spawns helps prevent the "run and gun" mentality of some players. Also this game will go fast and that will facilitate getting players back into rotation faster.
