This game is a must get for any gamer looking for an amazing campaign. Thrust into the next world war, the player finds him/herself, fighting on multiple fronts, as either the special ops group or as the marines, each side has its own unique fighting scheme, and each mission has the player using different strategies, such as stealth or a full-out attack. The enemy ai are surprisingly smart and if you're not careful you'll find yourself dieing constantly. Your friendly ai are just as smart, and will actually cover you and suppress enemy infantry. The different difficulties are all very well designed so that any gamer, from the beginners to most experienced, will find themselves challenged. The weapons on each level are plentiful, so if you don't like the one you have, you can switch it out pretty quickly. The one downside is the air port level, where you are forced to slaughter tons on innocent civilians. This level however can be skipped at no penalty to the player.
The special ops is a very nice addition. It takes various campaign maps, and incorporates a different mission into it. What makes this lots of fun is the ability to play cooperatively with a friend over Xbox live, system link or split screen.
The multiplayer is lots of fun whether you play online or offline. Each mode has its own independent leveling up system, with the ability to unlock weapons, weapon attachments such as scopes and silencers, perks, and different titles and call signs. The online experience is very smooth and doesn't have very many glitches.
