Single Player Mode - Campaign:
The single player mode is quite short, it takes 6-7 hours on a reasonable difficulty level although it offers compelling scenes and a gripping storyline. You play as three characters one being your Captain in a look into the past at an old assansination mission on a nuclear war dealer. (a personal favourite level of mine) It has an extremely emotional end.
Graphics:
The game overall is incredibly well presented and glitches are very hard to find and best discovered on youtube. Battles are extremely life like and you recieve the full feel of the battle. Battle scenes are mixed with tanks and also helicopters which you can fly in and you can also destroy enemy helicopters with a rocket launcher or a grenade launcher.
Multiplayer:
For me the multiplayer is the best feature of Call Of Duty 4 it has split screen for you and friends. You can either play on teams or against eachother, on the multiplayer you can play on maps you battled at on the campaign, although you can also play online you fight battles with different settings such as "Free For All", "Team Deathmatch", "Sabotage" and many more, there are so many settings which could include planting bombs while the opposition team try their best to prevent you from doing so, or simply teams fighting eachother. But once you have finished your battle you get points which get your level up and when you get a higher level the more weapons and scopes you unlock for use in the battles.
Gameplay:
Call Of Duty has excellent gameplay, the contols are easy to use with the usual R1-Shoot L2-Scope R2-Explosive Grenade L2-Special Grenade. (either smoke,flash or stun)
