Die Hard Vendetta is a mixed bag of lollies. The level designs are fantastic, yet there's hardly any interaction with them. Enemies are some the dumbest ever, sometimes they'll just stand there while your killing the person next to them and stuff. The frame rate is dreadful, and the textures are very N64-ish. Bleh. The soundtrack's pretty good, though.
Stick to Die Hard Trilogy and Die Hard Arcade. You can swear all you want while playing them. More than 25 times, even. =O
