well problem is crows, you would have a hard time shooting them all.
but if a Resident evil extinction map was made, i'd personally spit in the makers eye and drop the maker and their house into a pit with 5 story spikes, and gas would pour from sides of pit and if it doesn't drown you, or fumes don't kill you, a spark goes off and explodes whats left.
This was the worst resident evil movie. Definetly tell was new director. She wen't slow-mo when jumping 2 feet down and landed on the top of a truck... wow really awesome, and the action basicly ended there for that scene.
All the fights didn't compare to the second, i mean thats the point of sequals of movies, to make a better one, not a worse one.
