Fatboy: This one is a must-see. Causing players to gain weight as they score kills and loose weight when they die, you'll soon find stick figures and massive sumo-esque fighters populating the match. Not only does this add some additional realism to the game (in that people are many different weights), it makes good players much easier to see and hit, evening the odds a little for those who aren't quite as skilled.

Flak Arena: Replaces all weapons and ammunition on the map into Flak Cannons and Flak Shells and gives every player only the Flak Cannon to use, with a full load of ammo to begin with. This is all well and good until you run out, at which point you are left completely helpless.

InstaGib: All players are given a Enhanced Shock Rifle as their only weapon. This requires no ammunition, yet inflicts massive damage resulting instant death for the victim. This mutator is excellent if you are looking to improve your aim.

Instant Rockets: Allows no loading of multiple rockets or grenades. Instead, each rocket/grenade is launched as soon as the fire button/key is pressed.

JumpMatch: Give everyone permanent AntiGrav Boots, allowing them to jump much higher than normal. Combining this with Low Gravity results in players being able to jump to ridiculous heights. This mutator makes some maps which rely on wall fortifications (such as CTF-LavaGiant) much easier.

Low Gravity: Reduces the gravity in a match to a fraction of it's normal level, as is the default on DM-Morpheus. Not only can players jump higher, projectiles which are affected by gravity travelfurther and straighter, and the Translocator is able to be thrown much higher and further.

No Powerups: Removes all Damage Amplifiers, Invisibility Powerups, Big Keg O' Healths and Shield Belts from a map.

No Redeemer: Removes the Redeemer from the map. This is recommended for professional and serious matches.

Pulse Arena: All players are given Pulse Rifles as their only weapons and all other weapons and ammo on a map are transformed into Pulse Rifles and Pulse Ammo batteries.

Rocket Launcher Arena: Gives every player a fully loaded Rocket Launcher and changes all weapons placed in a map into RLs and all ammunition supplies into Rocket Packs.

Shock Arena: The Shock Rifle becomes the weapon du jour - it being the only weapon available on respawn, albeit fully loaded. Every weapon and ammunition pickup in the map are transformed into the Shock Rifle and Shock Cores.

Sniper Arena: Exactly like all of the other Weapon Arena mutators, except this time it applies to the Sniper Rifle and Rifle Rounds. Happy Sniping!

Stealth: Every player is invisible for the duration of the match. This makes identification of teammates in team games very difficult (though they can still be identified by moving the crosshair over them). We recommend that you use Team Beacon in conjunction with this if you plan on using it with an team Game Type.

Team Beacon: Places an beacon above the heads of all team mates, making them easy to identify even at a distance and when they are invisible. Included in Digital Extreme's Mutator Pack.

Volatile Ammo: All ammunition packs in the match become explosive, and are detonated when fired upon. Makes bases in team games somewhat less safe to be in. Included in Digital Extreme's Mutator Pack.

Volatile Weapons: When a player dies and drops their weapon, it explodes - Watch out! Included in Digital Extreme's Mutator Pack.
