If you want to get this cheat, you have to learn to strafe 100 percent of the time. This level is nearly impossible to beat in under 3:30 without strafing and easy it beat with if you strafe. Because of the immense size of the level, strafing will greatly reduce you time.
In this level strafe all the time and use your silenced PP7 to shoot only guards who block your path. Strafe down the path and when you reach the first sniper tower, very slightly turn a little bit right, and cut through the snow. A large distance across the snow is a small hut will a camera near the door, go in , execute the officer and take his key. Exit through door, shoot the other guy only if he blocks your path. Strafe back in the direction you came from, but going to the right a little bit, and you should encounter two more houses facing each other. Head towards the one farther away from you, ignoring the shots being fired at you, open the door and grab the key (objective b completed) on the table, then exit. Strafe down the path on your left, when you see the big communication building (with the giant satellite dish), Take a direct path to it, cutting across the snow. When you reach it, find the door on the side and go all the way up the stairs. At the very end, open the door and press B while standing in front of the computer console to turn it off (objective a completed). Back track to the exit of the building and take a left outside to follow the path going around the back of the building. Enter the fenced area when you see it and enter the building on your left. Inside, open the safe and take the bunker plans (objective c completed), then exit the house and exit the fenced area. Retrace your steps on the path back to the communcation building, after you pass the building's door, continue down the path and take the first left turn. Strafe down this path, killing any guards along the way, when you come to a fork, take a left and strafe to the ventilation tower, then climb it. Quickly aim and use your silenced PP7 to destroy all four locks in any order, ignoring anybody who also climbs up and is shooting at you. When the metal grill falls down, jump down to the bunker (objective d completed).
2x Grenade Launcher
This is for takes a thrill in playin' dirty, using the big guns. This a very fun cheat to use, the grenade launchers have good accuracy and are mostly easy to manage. This is an awesome tool for destroying big equipment, killing hordes of enemies at once, and blowing any unsuspecting enemies at long range. These have a six grenade clip and hld 18 grenades in each gun, but with the infinite ammo cheat, you have a never ending supply of grenades to shoot. When you shoot grenades they arc in the air, bounce off walls, and explode when they hit the ground. You can shoot one straight up in the air and have it land on you! Grenade launchers are much easy easier to use than rocket launchers, it is easier to hit a targets. However, there are some things that make the rocket launcher better, with the grenade launcher, you have a limited range of where you can shoot as long distance will stop you from destoying things that are very far away, and you sometimes can't destroy things mounted on ceiling or high on the walls (such as cameras and drone guns) because the grenades will bounce. But all in all, it is a very cool cheat to use.
