One word to describe this: Brilliant.

User Rating: 9.5 | Call of Duty PC
If there is one First-Person war-game I could have, and only that one, it would have to be this. Call of Duty is prehaps the most complete World War II games ever, and brilliant in every way. With 24 missions spanning the whole war, and the chance to play as each of the main Allies; the USA, the UK and Russia. You get the full range of guns from each army, and each has its own advantages and disadvantages, as in real life. The game, visually, looks beautiful. It's amazing crafted and you can see the horror in each soldier's eyes when he shot down. The sounds keep the game at a great level, with the music added such an atmosphere to any position you're in, and the rumbles and explosions from air-strikes in the background adds to the feel of being in a war-zone. And the multi-player is absolutely fantastic too, the online game being so complete, just like the single player. I've had hours of fun from playing this both on and off line, playing as different types of soldiers and using different tactics. A brilliant game.
