Grifball
From Halopedia, the Halo wiki
"In 2552, the Red Army introduced Grifball to the world. By 2557, all other sports had been abandonded."
Grifball is a new home made game type made by the RoosterTeeth personell. It is an assault variant, on played on a varient of Foundry. The origin of Grifball is as follows quoted from Burnie Burns, creator of Grifball.
"In Season 4 of Red vs Blue, Sarge is taking potshots with a sniper rifle at his orange soldier Grif, whom he hates. He’s having a great time and blurts out “This is the best game since Grifball!” That was written about two years ago and we always wondered what kind of game Grifball would have been. That’s why the ball carrier turns orange – everyone in the game is constantly trying to hammer-smash Grif and even if he scores, he explodes. Either way, Sarge wins."
Rules
Grifball is a simple game. Two teams of 3-4 players square off in a simple arena in which each team has a goal. The object is to take the ball in the middle of court and put it in the other team’s goal.
1. Scoring a goal earns one point and ends the round.
2. Each match consists of five rounds. The team with at least three points at the end of five rounds wins the match.
3. Each player has a gravity hammer and an energy sword (secondary).
4. Damage is set to 300% with player health set to 10%. One direct hit will kill a player.
5. Dead players respawn in three seconds at their own goal.
6. The ball carrier has a 3x Overshield, 150% speed and turns orange.
7. Friendly players can hurt each other. Learn to use your radar.
8. In the unlikely event that a player finds themselves thrown outside of the arena (beyond the wall), find a teleporter. It will drop you out in the middle of the arena. Play is not suspended when a player goes out of bounds. It is your duty to return to play.
9. If a ball carrier goes out of bounds, the must return to play within 30 seconds (judged by time on Save Film) or they forfeit the entire match. If they leave the ball beyond the wall, it will reset within 30 seconds. Play is not suspended while the ball or ball carrier is out of bounds.
