If we're gonna talk about gamemodes,i have an idea: Manhunt
It's like a slap,but only one person is capable of slapping everyone.This person is the Hunter.
The other players are the Targets.They run from the Hunter.
The hunter has 30 seconds to hunt (slap) someone,and that time resets when he does.The person slapped is out of the game.
Every time you hunt a player,the other players have 5 seconds of Invincibility and you lose some speed for 10 seconds.
If the time is up and no one was hunted,the Targets win.
If the hunter goes out of bounds,he loses 3 seconds.
