various melee attacks without shapeshifting, as well as more gymnastic moves such as air combos, sliding along the ground using any humanoid enemy's body, and a high-speed rolling cannonball attack. Alex can also transform parts of his body into a selection of martial implements acquired over the course of the game, either as purchased upgrades or being given them. Offensive powers include the large and powerful Blade arm, fast razor-sharp Claws (which can also erupt large spikes from the ground), the telescoping Whipfist, Musclemass that augments his strength, and the slow but powerful Hammerfists. Defensive options consist of a large shield on Alex's left arm for blocking ballistic attacks that needs to regenerate after excessive damage, and full body armor that exchanges agility and speed for toughness in hand-to-hand combat; both will allow Alex to plow through most obstacles when active. Vision modes include thermal vision, which allows Alex to see enemies through smoke and other obstacles at the expense of a decreased vision range, and Infected vision, which highlights those infected with the Blacklight virus as well as military units. Both vision modes muffle all of Alex's other senses, such as hearing, in order to concentrate on his sight. One defensive and offensive power may be active at a time, and using either will negate Alex's current disguise. In addition to his own abilities, Alex can take the weapons from defeated or absorbed enemies. These include automatic rifles, machine guns, grenade launchers and missile launchers. He can also seize control of military vehicles, such as tanks and helicopters. Alex's most powerful attacks are the Devastators, which require Alex to be in Critical Mass- either a state of near-death or the exact opposite, having excess stored biomass and increased health. These include the Tendril Barrage, which fires impaling tendrils from his body in all directions, the Groundspike Graveyard, which erupts massive spikes from the ground all around Alex, and the Critical Pain, which fires a single beam of hardened biomass from his hands to severely damage a single target. For movement around the city, Alex uses his increased physical abilities. When sprinting, he will automatically hop over cars, barriers and other obstacles without losing momentum. Alex will also scale any wall he comes into contact with and simply knock aside any humanoids that get in his way without stopping. He can jump great heights and distances, enough to clear five-story
