hmm...how about a "Black Friday" map?
Situation: There is one last PS3/Xbox 360 (whichever you like more) on sale for $150. You don't have enough money in your pockets so you have to grab it and wait for your friend to show up with more money. In the mean time, others are trying to eliminate you to get the console for themselves.
Basically, the map is an electronics store, the "hill" can be a checkout counter or an aisle, and the flag is a PS3/Xbox 360.
Just throwing it out there.
