1) The safe way: to do this, you need to have done something on the previous level, Infiltration. You must make sure that you only punch out the man by the interceptor with the keycard rather than killing him. Remember that if you punch him, he still dies if you then blow up the interceptor next to him. He will then appear on Imvestigation to open a locked door for you.

At the top of the lift turn right and kill the guard at the end. Go up to the door and turn on the x-ray scanner. You should see someone there if you saved the man on infiltration. Press B to open the door and it will tell you it is locked. A few seconds later, the man behind the door will open it and you can go through. This is the room where the spaceship is on Maian SOS. Follow the path round to where Maian SOS finishes and on a shelf on the end pillar of the room at the top of the lift should be a phoenix. On explosive shells, this is a one-hit-kills even on perfect agent. After this head back to the main room. Several guards will probably have followed you into this area, so kill them and go past the lift. Kill the guard on your left and then the 2 together just ahead. Head into the 2nd elevator room. Aim up and you should be able to take out 3 of the 4 guards around the top, and then the fourth one when he gets into the elevator, because you can just shoot the floor. Shoot the hole and then continue as in the main strategy.

2) The faster way: Go left at the top of the lift and kill the two dragon guards straight ahead almost together, just in front of the door. collect the ammo and wait until the timer shows 27 seconds (on a PAL cartridge). Then go through and into the lift which should be opening or just about to open. go to the front left corner and double crouch. When the lift door closes, go up a bit then throw your dragon on proximity into the front right corner. As you get to the top, you should not have been hit, but retreat into the back left corner so that the exploding dragon doesn't kill you. It should take out all four guards at the top, and you can proceed to destroy the wall with another proxy dragon on the opposite side to the lift.

Anyway, destroy the wall with a proxy dragon and go left, taking out any guards you see. Continue until there is a door on your right and a door on your left. Go to the right and shoot the next two guards in the head. Activate the nearest thing on the left and then go back to the door you came in through because I find there is usually a guard here. If there is, kill him, and then go back to find the containment thing you raised. Activate X-Ray Scanner and complete Objective 2. Go back towards the hole you made, and then beyond it and up. If there are guards, kil them, but make your way to the door on the right of the slope going down to the right. Kill the drone gun with a grenade and download the virus. Go out and back up to the door on the right at the top of the ramp - go in and destroy the computer console, as well as the guards (beware - don't fire grenades "through" the door, because the door may close very suddenly and the grenade will bounce back). Go back down the slope to the left, right to the bottom. Before you reach the big door, there are two little doors on either side. Shoot to attract the guards' attention and hope one opens one door. You may want to use x-ray scan to help tell which door is going to open because if you look at one and the one behind opens, you will lose lots of health. If neither door opens, you will have to take the long hard way round of going through the big door, up the ramp and in through the vent while double crouched - this is stupid if you have to do it. Once inside, kill people in there. Open all the lockers near the scientist guy until you find the disguise, and then put it on. Go out and back towards the hole you made originally, and then go through the next door on the right. If either guard is walking away from you, punch him out, but if not, ignore them (use disarm as your weapon). Go through and get the keycard, then on perfect agent you may want to kill the guards who try to kill you rather than run straight through the middle. Go back out of this long room and into the main corridor, then turn right, through the door and right again into the final long room bit. Use grenades to take out the guards in here, including the ones hidden behind the dividers, and then enter the final room. If you have no health left, this may be hard, but shoot all the guards in here. Otherwise, run for the one closest to the locked door, because he always has the keycard, and kill just him before finishing the level. The time you should achieve would be around the cheat time.
