OBJECTIVE: Infiltrate the Armacham complex
Action will begin instantly. As soon as you take control over your character, switch to Slo-Mo and go forward, shooting all the time. It's essential that you turn right and hide behind the wall - finish the upcoming soldiers off by using a shotgun.
If nobody comes out of the building, get inside and restore order. Watch out for the soldiers - one or two may run up the stairs and appear on the roof on the other side. When everything calms down, pick up the soldiers' weapons - VK-12 Combat Shotguns and G2A2 Assault Rifles.
At the reception desk you'll find an RPL Sub-Machinegun, a 10mm HV Penetrator and a Body Armor on the left, and a Medkit and a AT-14 Pistol on the desk. Next, go out and go right. If you wait long enough, the last adversaries will run upstairs without your help. Then, finishing them off - Slo-Mo plus a shotgun - is a piece of cake. Take their G2A2 Assault Rifles and go downstairs.
Walk on the roof and stick to the left wall until you get to the building entrance. Go through the corridor and make sure you take the Medkit and the Body Armor, which are on the right.
When you get to the place (the picture on the left above) first, turn left and take the Medkit from the shelf (the picture on the right above). After that, crouch and cross the bridge. Lie in wait by the staircase with your shotgun pulled out.
Two soldiers will start going up the stairs. As soon as you see the second soldier's head, turn Slo-Mo on and shoot at it, and next shoot at the head of the first one (it's the correct order). Go downstairs and lean out carefully - there are two more enemies in the room. Kill them using the rifle and take four G2A2 Assault Rifles.
Go down the stairs. Stand by the wall and lean out with your rifle pulled out. Switch to Slo-Mo and shoot another two soldiers. Before you go the short stairs down, take the Medkit lying on the floor on the left.
On the floor there's a 10mm HV Penetrator. Take G2A2 Assault Rifles from your enemies and carefully open the door. You'll have no difficulty in killing the soldier by shooting at his head (turn Slo-Mo on, of course).
Turn Slo-Mo off and wait for the next enemy to come. It doesn't matter if he stands behind the rail or jumps over it - turn Slo-Mo on and get rid of him. Next, go up the stairs and, as soon as you notice another enemy - switch to Slo-Mo once more and kill him.
You must find the last adversary on the roof and eliminate him. Afterwards, take all their weapons - three G2A2 Assault Rifles and one VK-12 Combat Shotgun. Find the barrel which you can see in the picture on the right above. You'll acquire a Body Armor, a G2A2 Assault Rifle and three N6A3 Fragmentation Grenades.
Go up the stairs to the upper part of the roof and watch out - there'll be another adversary here. Once you see him, turn Slo-Mo on and shoot him at the head. Take his weapon and get to the entrance on the right.
You'll arrive at a room. Zoom in the screen and wait - two soldiers followed by the third one will appear on the right. You should be able to kill the first two before you run out of Slo-Mo. Run way from the third, however. Come back to take care of him only when Slo-Mo has reloaded. Take the Medkit that's on the right.
Take your enemies' weapons - two G2A2 Assault Rifles and a VK-12 Combat Shotgun. Find the barrel which you can see in the picture on the left above, and you'll acquire a Reflex Booster that's lying on it. Next, go right, then left and take the stairs. In the next room kill a soldier who's between the pillar and the wall. On the left there'll be another one - pick up the weapons and go up the stairs on the left.
You'll get to a table - there are: a Body Armor, a Medkit, and a RPL Sub-Machinegun, a next to it you'll see a G2A2 Assault Rifle. Take everything and go right, then turn right again. Take the Medkit from the wall.
Save the game as you're likely to be hit by a grenade during the following combat. Pull out you Sniper Rifle and turn on the sight. Crouch and carefully move forward. When you see the soldier's head - turn Slo-Mo on and shoot at it. There'll be three more enemies to go. You need to get close with caution and take them down one at a time just as you've done it before - only now use an ordinary rifle instead of the sniper one.
Go down the stairs on the right. Go around the roof and pick up the enemies' G2A2 Assault Rifles. Next, break the window pane down and jump inside the building.
