Magnus is correct but un-specific in his undeadliness facts, :p
garlic and crosses only work on Vampires but not Zombies who need to have their brains destroyed to stop them.
Frankenstein-type monsters need pitchforks and fire.
for Werewolves one needs to pierce their hearts with some silver object.
one can stop the Blob with high-voltage electricity, it's fun to watch.
it was all explained above mate. the zombie is easy, bust the head (brain) one way or another and the job's done. the german guy on the other hand might be a whole other can of beans...
