RESIDENT EVIL: EXTINCTION

Okay, try to keep up. I'm a genetically-engineered supersoldier with incredible telekinetic and martial arts powers and no tits. My DNA also happens to be the only cure to zombification, which is great because it just so happens that the entire world is zombies now.
Hey, I'm a chief scientist in an evil multinational science corporation. We created the zombies because science. Now that the world is zombies, we need your DNA to undo everything. Also, science.
No way, dude! I'm not gonna sacrifice my own life to save billions! I'd rather decapitate hundreds of zombies with my extraordinary melee combat skills.
That's fine. I'll just keep racing against the clock to find a cure some other way. In the meantime I'll counter-productively and randomly murder lots of my own researchers even though they are in desperately limited supply.
Hey, I look like a porn star, but really I'm a battle-hardened veteran leader of a zombie survivor group.
And I'm the team's wisecracking token black stereotype. Join us!
Sure, no prob- OH SHIT ZOMBIE BIRDS

Awesome!
I'm going to hunt Alice down using our advanced sattellite technology that still inexplicably works despite a world population of approximately five humans.
Oh no! I got bitten by a zombie! Despite the fact that the world has been taken over by zombies, I'm still completely oblivious to the ramifications of this. Just to be safe, I better not tell anybody.
Hey, token black guy! You look sick!
 
FUCK! Alice, do something!
I can only look on in abject horror!
But you're super telekinetic! You can just make the zombies' heads explode with the power of your mind! Like you have on multiple prior occasions!
But that would eradicate the need for the filmmakers to violently and graphically slaughter dozens of innocent people in loving detail in a zombie brain-eating montage! All modern zombie films must do this to imply that mankind is the greatest evil of all.
Oh. Makes sense. EEEE!
 
Everyone's dead now, you bastard!
And now I will kill you in order to carry out my evil plan to rid the world of zombies!
Over my dead body!
(poorly-explained super-mutation)
Oh no! My powers are useless against an old man who has been chemically mutated to the point where he can barely even function!

Hurrah!
Oh yeah! Movies based on video games are consistantly AWESOME!
