A mysterious businessman hires a team of ex-soldiers to accompany him on a "48 hour mission" to an abandoned World War II bunker in Eastern Europe. When they arrive, they discover the underground location was where Nazis were doing some kind of sinister experiments. And they also find a seemingly unstoppable enemy intent on killing them off in gruesome ways.
First off, the set design and lighting is excellent. The early scenes where they explore the dark bunker are wonderfully atmospheric and eerie. The first appearances of the Nazis (as glimpses in the background) really crank up the suspense, and totally got my attention. The violence and gore effects don't actually begin until after the halfway mark, so it's a credit to the film that it kept me hooked for that long on atmosphere and mystery alone.
The acting performances overall are good, though the team of soldiers seem to have been chosen based on their contrasting strong accents. This handful of characters manages to feature accents from Africa, Russia, Northern Ireland, Scotland, and English public school, and some of the conversations sound almost comical. The cinematography uses an interesting, washed out, almost sepia colour palette. And as far as I can tell the special effects are all practical rather than CGI.
The only disappointing part is a bit of inconsistency with the zombies (in the later part of the film, do they forget they're able to appear and disappear in closed rooms?). And while the ending is satisfying, it feels a little unoriginal. The score is surprisingly grand and orchestral, and while this gives an impressive sheen to the production values at times, it does seem slightly out of place in a low-budget straight-to-DVD horror movie sometimes.
But don't let any of that put you off - I had a ball watching this! Outpost is far better than most films of the same genre and budget. Whatever its limitations, it still looks amazing, and it's a tense - if slightly silly - scary ride.
