VS3: Infantry of Doom (1999) aka Zombie Doom !

Utterly ridiculous, yet you can't help but love it !
Best thing about the DVD release is that it comes with an extra that is the full film of Zombie '90: Extreme Pestilence http://www.imdb.com/title/tt0103336/ that has ONE guy do all the english dub and it's beyond hilarious. The dub had me in tears in places. It's obvious the guy is having a bit of a laugh with the dub, but it's so worth seeing it because of that :)
