Action Sack

"Action Sack is back, offering up a whopping 0 EXP and a sloppy mess of crazy social fun."

- In-game description for Halo 3's Action Sack playlist

Action Sack is a playlist featuring unusual and creative game types.

In Halo 3, Action Sack is a social 4v4 playlist that features 3-4 Players per team with a max party size of 8. Unlike other playlists it yields no experience points. All DLC maps including the Heroic, Legendary and Mythic Map Packs are required to play in this playlist. It features many forged maps and many of the default map and the DLC maps.

Action Sack made a return in Halo: Reach, even featuring its own announcer line and gametype, but the playlist was removed in the August 2012 update.

New Halo 3 Gametypes

 * Pit of Lies (Team King of the Hill) - Team King of the Hill. Players lose one point per second while standing in the hill, but gain two points for killing a player while in the hill. Outside of the hill, players do 0% damage. Inside the hill, players do 200% damage and have 50% damage resistance. Hill moves once every minute. First team to 10 points wins. 10 minute match time limit.
 * Tug of War (Team Slayer) - Players spawn with Battle Rifles. Points are gained by killing opponents, but lost by dying. Bonus points are awarded for killing sprees or eliminations. First team to 25 points wins. 10 minute match time limit.
 * Run for Cover (One-Sided VIP) - Appears on a specialized Sandbox map: Zeus. The VIP team spawns on the ground level with plasma pistols, and cannot damage their opponents. Points are awarded every time the VIP reaches an escort point, but are docked every time the VIP dies. Next VIP is chosen at random. Anti-VIP team spawns on the sky floor with Sniper Rifles and Spartan Lasers, and are attempting to stop the VIP and lower the VIP team’s score as much as possible. When the VIPs escorts are nearby, they take on his color (gold) and their move speed increases, lasts for 4 rounds.
 * Team Sumo (Territories) - Players spawn with gravity hammers and are invincible. Teams ride into the single territory on Warthogs and must knock their opponents out of the ring. Highest score after seven rounds wins. If a player dies, they respawn inside a box that can't be escaped, but players can still watch other players like an audience.
 * Punch-out (Team Slayer)- Teams spawn with Plasma Pistols and must melee the enemy to gain points.
 * Team Stickies (Team Slayer) - Weapons do 0% damage. Only sticks count.
 * Dodgeball (Team Slayer) - Teams spawn with Plasma Pistols and regenerating sticky grenades, and played on a map specific to this gametype, facing each other across a ditch that cannot be passed, if you are dropped in, there is no way out and you are vulnerable. There is 300% gravity and 4X overshields. Players must stick or shoot (which is unnecessary unless you are to overcharge it to drain their shields) other players to gain points, but simply killing other players will end the round, and killing the last man on the other team earns 5 bonus points.
