Sluggish walks, constant incoherent moaning, the only urge is to feed (supposibly, altho some will just kill you with a weapon and walk off ironicly) but can carefully aim a gun on par with a live human.
Careful what you say, mods can now delete posts based on what they think are insults rather then actual fact based insults, Terrible system at it's finest.
They did this in one of the George Romero films with the zombie who learns how to use a machine gun lol (Seriously everytime I watch the films, It gives me an urge to play RE2 specifically and now RE6 I suppose)
But yeah the police officers aiming is amazing.
But you could stand infront of a C-Virus machine gun wielding B.S.A.A zombie and he will unload his weapon infront of you and not touch you with one bullet. But the ones in Mercs mode always knock me down.
C-Virus Magnum wielding zombies have better aim then the J'avo.
