1) From where you start run forward and shoot the two guys who are running towards you. Get their guns and run to the right. Shoot any guys you see. Get behind a tree and shoot anyone you see. Then shoot the drone gun.
2) After the drone gun is dead run behind it and to the corner of the map. There should be a bulletproof vest, get it, and then run down to the next drone gun.
3) Shoot all the guys on your way to the next drone gun. Stay to your right and when you get near it you should see two trees right next to each other. Aim through them and shoot the gun. Then shoot anyone who attacks you.
4) If you need another vest there is one directly behind the drone gun.
5) Run to the next drone gun and then shoot anyone there. After everyone is dead shoot the drone gun.
6) There is a vest in the left corner of the map.
7) Run to the bridge. Go across it until you hear the music change. Then run back and go to the left or right. Aim at where Onatopp will appear. When she appears aim at her head and start shooting.
8) Once she is dead run across the bridge and turn right but don't move that way. You should see a drone gun, shoot it.
9) Go to the entrance of the cave and look in. You will have to go a good ways into the cave before you can see the guards to your right and left. Shoot them and then run to your right. A drone gun will shoot at you. Get out of its sight and then creep out of the cove your in and shoot it. Run up the passage way the drone gun was guarding. When you see it lead into a big room slow down. There will be a guy to your left (shoot him first) and right (shoot him last), shoot them and then go to your right. You will come to a room with a lot of crates. Shoot the guys on the left without the guys on the right seeing you. Once they are dead shoot the guys on the right. There will probably be about 7 or 8. Then run up the incline.
10) When your up the ramp you will see a row of explosive tanks. Shoot them.
11) After the smoke clears walk over to where they were and turn left. Shoot the drone gun. Then go a little farther out and turn left there will be another drone gun. Shoot it.
12) Then go back to where the tanks where and switch to your RC-P90. Run into the room with all the guys and blast them. They will not have a single prayer. Run to where the elevator is and jump on.
