Custom Game Modes

Hello everybody. I am creating this topic to discuss Custom Game Modes. Custom Game Modes are custom games, with special rules, and winning objectives. For example: Hide and Seek. You play on Crystal scar, with one team of 5 hiders, and one team of 2 seekers. the hiders get a certain amount of time to hide in the map, and the seekers have to try to find them after.

There are many Custom Game Modes, but I want to hear some that you guys really like, or ones that you've made up. Thanks!
