Ok, just finished watching 'Outpost'.
http://en.wikipedia.org/wiki/Outpost_(film)
Admittedly low budget, but good movie. (Disclaimer: My favourite movie is 'Big Trouble in Little China'.)
So, Nazi war bunker holds device for creating super soldiers.
Spoiler Alert!
These guys were, via Grand Unified Theory machine, altered. They died, but their identidies become encased in the local magnetic field. Very soldier like, that is the main part of them that survives, and animates the bodies. Intelligent enough for strategy, and still deadicated Nazis. (Couldn't resist!)
Here's the thing, brain shot does nothing. They don't bite, and apparently due to old ammo, are very stabby instead. They kill you, you die and stay dead. No re-animation for your dead fellow soldiers. Bullets don't really slow them.
So...how do you defend against non-zom....Ok, Ok, I know that's the politically incorrect, deadist term..the otherly-animated? If shooting doesn't kill them, what do you do?
