Upon starting the level, the player will notice he has no ammo in his M1 Garand, but a parachute drop containing ammo and guns will drop, the guns are: Thompson, M1 Garand, M1919 Browning Machine Gun and a Scoped Springfield. It is advised to pick up at least the Thompson, and then go to the main bag and pick up ammo. The crate has infinite ammo. After picking up some guns, you will wipe out some troops and descend into an underground building. After getting out of it, there will be a large firefight and after this you will have to destroy Japanese mortar positions. Use mortar rounds on tables scattered around the place and in the pits themselves to ease the work, but beware they are very, very powerful. After this, you will enter what resembles the multiplayer map Courtyard, and after this you will go into a large open field with the courtyard buildings and some sandbags, and this is where the real twist of the knife is. Some Japanese soldiers will appear to be surrendering, but it is a trap, and as Polonsky goes to one and Roebuck goes to the other two, they lash out, and the player must save one of them. If you save Roebuck, Polonsky will die, and vice versa. Saving Roebuck is harder, as there are two soldiers, and a grenade is scripted to go off. When you save Roebuck, he is distraught at Polonsky's death and turns into what Reznov is, ordering you to show no mercy and kill all enemy soldiers, and after you call in the airstrikes on the buildings the surviving one of them will give you the other's tag, hinting that they don't deserve it and are extremely upset and feel guilty of the other's death, even though they couldn't do anything, but whatever the scenario it is extremely emotional.
