The HUD features a special gauge representing the boost-meter. Using the boost will deplenish the meter. It can be filled again by picking up special boost-pickups. There are two kinds of pickups: 12% refills and 100% refills. The latter are located at the edges of the arena, while the smaller ones are placed more inward. Picking up a 100% boost will consume the node and bring the boost meter to 100% regardless of the prior level of boost. Nodes will not be consumed if the boost meter is already at 100%. The small 12% nodes refresh on a ~5 second cooldown, and the 100% orb nodes refresh on a ~10 second cooldown.The Mutator Settings will allow the player to change the amount of "power" the boost has and make boost auto-rechargeable. The cooldown for recharging boost with that mutator on is ~3 seconds after deactivating boost.
