If you want a Tron like game then this is it. Slow moving with no real direction or story is great for visual of tron like neon things.

Great single player for it's day. A must have if you want to follow HL2 story. Very hard game with puzzle solving. Werid and wild.

Hard game but fun. Like COD.. Good maps. robust weapons loadout options.

Great way to introduce yourself to the story and fun single player game. Way cool!
