Players control Sam Gideon, a DARPA agent armed with the Augmented Reaction Suit. If the player takes too much damage, the suit will automatically enter Augmented Reaction (AR) mode. AR mode increases Sam’s reflexes tenfold, essentially slowing down time for Sam to evade attacks. The player can also manually enter AR mode by holding down the aim button while evading, sliding, or vaulting over cover, allowing the player to target enemies (and their weak spots) easily.
At any time, the player can use boosters on the suit to quickly slide across an area. If the player uses AR mode or the boosters too much in a short time, the suit will overheat and will require a short period to cool down, during which Sam is less mobile (and cannot use the boosters or AR mode). The suit will also overheat instantly if a melee attack from the player connects with an enemy, and certain areas of the game will also overheat the suit.
