Odd Ball
A 4-way 2v2 map that lets you hold onto a ball that has multiple spawn points. 5 in total, each corner and the center.
Only 1 ball spawns at a time, and if someone touches it, a countdown starts. every second it's held, you gain a point. after 15 seconds, the ball explodes. then it respawns after 3 seconds, in one of the 5 spawns randomly.
repeat this until one team reaches 50 points total.
1 round only, it's a long game mode, rather than multiple rounds.
you can throw the ball like a bomb, but you cannot see the countdown. the last 5 seconds give 2 points each, and after letting go, you get your points altogether. if you hold it for 5 seconds, when you let go, you get all 5 points afterward.
Map Design
it would be a semi obstacle course, but without killing hazards like poison or a breaking bridge.
instead, you get rotation fans, or blocks that wobble, and you can use this to navigate around, while other players chase you around attempting to take the ball. in the same vein, you may get knocked out yourself.
Alternatively, you can make the ball a potato, and call it Hot Potato
