Cheap'n'cheerful! Doesn't take up much space on the HDD either! The game is from the POV of a German soldier, which will appeal to many, for some reason or other, but this may also put people off. Forget politics - if you liked Wolfenstein RTCW, this may tick the right boxes for you. It's not very complex, but it's fun for a quick run around, shooting zombies on fire, and so forth. I'm still on the first level, haven't seen any truly eldritch horrors yet...
If you are one of these "punch a nazi" kind of people, it probably won't appeal to you, simply because the protagonist is German - but don't go expecting "Necrovision - The Glory Of The Goose-step", either!
Politics doesn't enter into it, the game focuses on survival.
Give it a go!
