Main method[]
1. Head southeast toward the agency pickup: a crossbow, bolts, and nightvision goggles. It's behind the western entrance of the tunnel, near a parked truck. Across the valley is a sniper tower. Use the trees for cover and move quickly to avoid fire. Being spotted by a sniper does not raise a general alert and so does not count against a Silent Assassin rating, but move cautiously, because Agent 47 can be killed by a single sniper shot on Professional difficulty. There is a guard patrolling near the Agency pickup. Hide behind the corner of the building, and wait for the guard to approach the truck. When he turns around, creep out behind him and grab the equipment opposite, and then quickly return to cover behind the building. Or sedate him and take his clothes. While these won't fool the patrolling guards, they will nullify the threat of the snipers.
2. Go northwest, back amongst the trees and look for where the road curves. Position 47 on the north side of a tree and wait for the one of the trucks to arrive. The truck stops on an incline, raising its rear. This prevents 47 from climbing inside, so the truck needs to begin accelerating before he can climb in. Move too soon, and Agent 47 will be gunned down by the sniper, but wait too long and the truck will accelerate away. The trick is to wait by a tree and begin counting to five from the moment the truck stops, and then run for it. If timed correctly, the sniper will not have time to open fire. Once inside, move to the rear of the truck and wait.
3. The truck enters the western entrance of the tunnel and heads east. First, it turns right and heads south. Second, it turns left and heads east again. Immediately after the second turn, the truck momentarily stops. Jump out. Guard patrols are not entirely reliable; sometimes a guard in the tunnel will see Agent 47 in the truck and raise an alert. If this occurs, then try again. For unknown reason skipping the Agency pickup effects the guard patrols inside the tunnel, making it harder to pass through undetected.
4. After exiting the truck, turn left and look for a metal door beside a garage door. The garage door cannot be opened. Peek through the keyhole of the metal door and wait for a patrolling guard to enter and exit the room. When the guard is gone, enter the room and approach the door the guard exited from. Wait and listen for the sound of the guard using another door on the southeast corner of the adjacent garage. Enter the garage and crouch behind the crates in the northwest corner. The guard will reenter the garage, wander behind some crates in the southwest corner, and then exit through the northeast door. When the guard has left the garage, use the southeast door and climb the ladder in the next room.
5. The ladder deposits Agent 47 back on the surface, under cover of a small building. Run around the building to its right and, near the base of another sniper tower, take cover behind the trees. Do not dawdle, because stepping out from the building exposes 47 to further sniper fire (if no disguise). Looking south, the valley turns eastward toward a dead end. Where it turns, a single guard is patrolling. Use the crossbow to kill him. To preserve the Silent Assasin rating, the guard must be killed with a single shot and no misses. If you have a disguise, you can take out your anaesthetic and let yourself be seen. The guard will run toward you and allow you go get behind him to sedate him. With the guard dead or sedated, follow the valley to the end, where another small building conceals a ladder.
6. Climb onto the ladder, but do not climb down. Wait for a guard to enter and exit the room below before climbing down. It's also possible to hide behind the door before he comes in and sneak ahead. The setup of the next garage and storage room is, excpeting the position of a few crates, the same as before. Enter the garage behind the guard and creep behind the crates stacked against the eastern wall. Wait for the guard to open the northeastern door and follow him quickly. Agent 47 must shadow the guard as he enters the next room, but slip off to the left through the north door and back into the tunnel. This requires precise timing and care to remain undetected.
7. Wait for a truck to approach heading east, and when it stops climb into the back. The truck will then proceed toward the eastern exit of the tunnel. As before, guard patrols are not entirely reliable; sometimes a guard will see 47 in the truck and raise an alert. If this occurs, then try again. When the truck arrives back at the surface, it will momentarily stop. Climb of the truck and simply head south to the exit for a Silent Assassin rating.
Silent Assassin method[]
This is a very annoying level and getting Silent Assassin will be tedious and difficult, however there are various ways to obtain it contrary to other more entertaining levels. There are three general ways to go about it:
-Above ground. Run through the treeline to avoid the sniper from seeing you. Do this running, there is a path that will allow you to get through unseen. Get your equipment if you want and sneak past the guard to an entry into the tunnel.
-Once you reach there, first make sure that it's safe to go down. You can ensure this by waiting at the top of the ladder as high as possible in such a position that the guard near the agency pickup can't see you.
-When reach there, sneak past the ninja and go out of the room into the main tunnel. Hide next to a pillar in such a way that the ninja can't see you. Wait for a truck, and once one comes it should stop near you. Get in the truck.
-Go and hide at the extreme back of the truck to be as safe and hidden from the guards as possible. It will stop once, don't panic, just hide in there. It will stop again, this time get out immediately, because right in front of you there's a truck checking point, and you can't afford to get seen! Too late and they will detect you, ruining your Silent Assassin rating.
-The guards would then be checking the trucks. Move towards them as far as you can go, till one point when there's no way to get past them, so wait for the checking to get over. As soon as the checking procedure gets completed, using the truck as cover run along with it, no guard will see you. You will get past them without trouble.
- Now keep on following the truck, and run fast to save time. Time is important in this mission because the glitches may ruin your rating even if you did not mess up anywhere. Follow it till the point where it stops. You might be able to get in, but if you cannot, don't worry, because it's quite inconsistent and doesn't happen everytime. Wait for the next truck if that is the case. And you can get into it when it stops.
- Once you've gotten into the truck, hide at the extreme back again to not get seen. Relax in there, till you reach the end of the tunnel. You now need to get out of the truck, otherwise the guards at the end of the tunnel will find you inside.
- There is another room at the end just like the one used to enter the tunnel at the starting of the mission. This time, however we'll use it to exit the tunnel instead. There's a truck there and a ninja patrolling around it. As soon as he goes to the right side of the truck, sneak to the left side, and once you've reached a blind spot, run to the room towards the left corner, where the ladder is. Congratulations! You have completed the mission. Now all you need to do is climb up the ladder to the surface and run to the exit!
Tip: If you are incredibly frustrated with the glitches that ruin your SA rating which are:
- Trucks stop moving
- Guards get run over by trucks and nearby guards get alerted, adding an alert to your rating
- Guards get run over by trucks and nearby guards get alerted.
- Guards get run over by trucks and their bodies get found, adding an alert to your rating
You can activate the bomb cheat and with one shot of a silent weapon kill the guards near the first checkpoint. You will not get any alerts, unless the guards at the main entry of the tunnel get run over, but it doesn't happen too frequently, and the trucks won't stop moving either. Using cheats is not encouraged, however it can be excused just for this one part as this mission is so glitched. It is fair if you're doing it only to avoid those glitches. You will still have to get through the rest of the mission honestly!If you did manage to get SA on this level without wanting to kill yourself after failing many times, congratulations, you can call yourself a true (Silent) assassin.
