Health increments have been reworked to function around the 25 health increments of Halo Reach while working around the new 100 maximum health value, allowing 4 health regeneration points over the original Reach's 3. This allows the player to be much more mobile in every direction and keep up with the new pace of the Prometheus mod's combat.
Acceleration adjusted to compensate for smoothness. New movement speeds of 0.6 walk speed, 2.4 max movement forward, and 2.2 max movement for strafe and backpedal.
Some have limited uses, and some like the new Berserk ability are entirely new to Halo.
