If you like watching poorly acted soldiers exchanging nonsensical banters about war while occasionally shooting Nazi zombies, you might last the first act. However, if you want actually plot or coherent dialogues, you'll do better watching bloopers from any other war movie. This is as vague as narrative as it can be, even by standard of B-movie.
There's basically no structure to the story at all. People would tell war stories for half of the movie, engage in obscure overly dramatic military propaganda and suddenly the shooting starts to happen. Characters pop out of nowhere and disappear altogether from the story, no one knows what happen to that one guy who was there earlier nor do they seem to care.
Zombie and Nazi are mixed into the narrative, yet the soldiers' reactions are inconsistent. It's as though someone shuffles random screenplays and just tosses them together. Acting is wooden, not that the material offers anything conclusive. It's marred with vague gibberish and at times dreamy near hallucinogenic scenes. Don't expect any finesse to technical aspect either, cinematography and effect are low budget mediocrity.
A lot of pretentious talk about war without war itself, it will painfully bores audience like zombie bites and by now capitalizing on zombie fevers feels like an old gimmick.
