Napalm Riot

First off, I always liked this better than MOHAA (back when they were neck-and-neck for best WW2 shooter). The class system and everything made for a very fun game, however the lack of upgrades and the useless AI made it very difficult to win if you weren't very good.

The graphics sucked, the sound was predictable, the controls were basic, the story was non-existent. Other than that, good game.
