You start inside with 006. After radio test with the phones, you give 006 a boost before you go off on your own. Like the Dam tunnel there's bound to be choices so there's no specific ways to get through the level. If you're expecting the Ouromov from the N64 version and the movie, there won't be an old guy. Instead more of a middle age, tough soldier leader.
Your First Break[edit]
At the end of the tunnel, you can choose to open the door and shoot. Or if you choose stealth go on the right side of the hole, press the button and as soon as button or motion prompt comes up, hit it before he takes his gun and shoots you. Also check the right side for a machine gun.
Stealth or Shoot?[edit]
There's two ways after you leave the bathroom (James Bond doesn't need a break anyway). You can go down the stairs or take the high way. Also look out for cameras to shoot. Go down the large canister area to the next epic place. Speaking of which, you can choose to go through the door or go through the tunnel in the roof. Also you can shoot the guy on the roof when you step out of the high tunnel. Another option is going to the further roof to go down and unlock the door. Or both. Anyway your goal is to get where the scientist is to force him to unlock a security area for 006 to get through. As soon as you reach the breach area, get ready for slow motion shooting. You automatically force him to unlock the door, with your help as the quick time events kick in. Finish taking down the enemies then go down to the centre path to the next section.
Scientists and Soldiers[edit]
You reach the science lab. As soon as 006 comes in, he asks you to distract them so he can escape. Aim your phone to the box area in which you allow the alarm to go off. Thankfully, you're on the other side of the glass, overlooking the area. Unfortunately, the last scientist gets beaten down. So much for the respect for the scientist! The next area is another shoot out. As soon as you're done shooting, go to the next area and take down a soldier ahead of you. You'll get to where 006 is.
Thanks 006[edit]
He'll take down two soldiers, one with the chair before letting you in. Your last task is to put timed mines on six big canisters. You can choose how you want to do it as there's soldiers and security cameras. When you're done, you run into a final moment. Ouromov has Alec Trevalyan at gun point counting down 'til he gets shot. Fortunately you're behind missile shells and a few nice touches in which his soldiers is restrain as shooting missiles will get them killed and one soldier who's about to kill you gets shot. After he supposedly shoots Alec, as soon as he gets close to you, press a button. You go on the moving conveyor belt and that ends the mission.
Agent[edit]
Along the way, look out for maps. A phone icon is blinking where you are. Make sure you check areas you haven't been through and take photos of three maps randomly scattered throughout this level.
