I love how no one in this thread has heard of "Assassination," but it's also (usually) called "VIP" because it's picks someone on the team to be escorted making him a VIP.
I would like for them to add a capture or race game.
Capture(or GTNW, Global Thermo Nuclear War): Played on a map with 1 point in the center(or some random set point on the map). Everyone has to go capture it (takes about 5 min to do so). The time it takes to capture is persistent, so even if you leave while capturing (say 2 min left), when you go back it will still take 2 min to capture. Do this until someone has captured it; That team wins. Those type of games are CHAOS!! But it can be fun.
Race(Race to the End): One linear map. GR and BL spawn beside each other (with a wall for spawn protection) Basically you have to run out to the end of the linear map ALIVE (BL and GR play side-by-side). Just a racing game with guns to slow the other team down. Once a person (or a certain amount of people) have reached the other side, that team wins. Can be pretty fun
