Since when do zombies stop in the middle of a street, pick up some random thing, and throw it back on the ground? I think just the "picking up" part is pretty unlikely to happen
Thank you for posting the footage from Valve's Left 4 Dead 3 that was shown at E3, I sadly missed it at the time! It is definitely excellent to see that there is even more creativity in regards to the gameplay.
