→Active and passive abilities
* '''Blitz''': If he doesn't take damage in 3 seconds, Blaskowicz's health will quickly regenerate to the nearest multiple of 25.
* '''H.E.V. Suit''': Freeman recieves no environmental damage. In addition, collecting LG ammo grants him armor, while collecting BFG ammo reduces his active cooldown time.
* '''Extraction''': When he's about to receive a lethal hit, Freeman is transported elsewhere in the map with 25 hp. This has a
45 seconds cooldown time.
* '''Crouchslide''': Kane can get a speed boost if he crouches at the moment when he lands from a jump.
* '''Kill Heals''': Caleb gets a portion of health back when dealing final blow. In DM, during active ability, heals fully.
