Corrected entry: Many of the zombies are shot in the chest, or shoulder, or in some other part of the body and just lay as if down. Zombies need to be shot in the head to be killed.

Correction: That is the rule in most zombie movies, but not all. For instance in ROTLD the zombies don't die even after being shot in the head, and in Resident Evil they can be killed by shooting them in the head or spinal cord. So the rules vary for different movies, and in House of the Dead it seems they can be killed by being shot anywhere.
