Ninjaball is a variant of Oddball. On it, players spawn with Active camouflage, move faster, and have weaker shields that recharge faster. This makes for a more strategy oriented game of Oddball.
In Halo 3, Ninjaball is different in that upon obtaining the ball the player has 2x speed, less gravity, but no Active camouflage. Needless to say, it is much more important to avoid getting hit by the one with the ball.
- On the map Snowbound, ninjaball is often vetoed as the ball carrier can simply get killed by the Guardians, then wait until the ball respawns, and then repeat until they win.
