Alex Mercer
The cutscene:
Alex is sprinting down a ruined, rubble strewn NY street, helicopters in pursuit. The helicopters open fire, Alex darts from left to right, leaping off fallen building walls and overturned trucks. The helicopters then unleash a barrage of missiles, Alex takes one out with projectile rubble, two more home in on him. Maintaining top speed, he dashes into an alley, the missiles hit one of the buildings and Alex continues running in down another street. The helicopters appear over the rooftops and one fires another missile. We see a close up of Alex turning his head to see the missile, he jumps up high and as the missile passes under him, he latches on with the whipfist and pulls the missile up and over him to collide with one of the helicopters, Alex dive bombs the remaining helicopter. Tanks and soldiers appear at both ends of the street, Alex grabs the ruined helicopter and leaps high into the air, he rips the rotors off and uses it as an improvised shuriken to take out one of the tanks before hurling the rest of the helicopter at the other tank. As he lands, the soldiers open fire, Alex dive bombs one group and hurls the ruined tank at the other.
Elizabeth Greene appears with a guard of four leader hunters. The hunters attack, Alex dismembers the first three with the blade arm and impales the last with a ground spike. Just as the the biomass from the ground spike retracts, he is tackled by Elizabeth who whispers, "Nothing can stop the spread, you will be the vessel", before stabbing him and infecting him with a strain of the virus that he can't control. With a cry of pain and defiance, he punches Elizabeth which sends her flying into the side of a nearby building, Alex takes a running leap at her and impales her with his claws, embedding them in the wall in the process. With Elizabeth dead and the virus still spreading through his body, he absorbs her corpse and boards the Reagan and takes it out to sea. He goes below deck to activate the bomb. "My name is Alex Mercer, and my work is almost done." *boom*
