• Hunter Killer : In this level, the player takes control of Derek "Frost" Westwood, as he and his squad infiltrates a Russian submarine to launch the Russian missiles against their own fleet. After escaping the submarine, Frost hops in a Zodiac watercraft and escapes the area as it is being bombed and ends up landing in a friendly Chinook, taking them away from the killzone.

• Mind the Gap : In this level, the player takes control of Michael Burns, an SAS Commando. This mission takes place during nighttime in London. The player approaches enemies using stealth. Not much is known about this level, except that it ends in an epic chase in the London tube system between an underground train and a car. Civilians are also killed during this level (This is the "ultra-violent" mission of the level that has been spoken of). The level's title is a reference to the warning made to train passengers to make them aware of the gap between the ground and the actual train.
