This level is pretty tough because it is loaded with men. You start in an elevator with a ZMG 9mm. Open the door, fire, then press against the wall. Wait for men to come in. After the men have come in, exit the elevator. Watch out for more men, then open the two doors. All the solider here are Janus Special Forces, and some where body armor. It may take quite a few shots to subdue a foe in this level. Kill any guys on the other side of the door, then head down the steps. You'll come to a door with two men guarding it. Kill them, then wait because a few men will come through the doors. After the men stop coming, go through, and down the steps. Make the scientist put his hands up, then walk through the path between the rock. Kill the guy on the other side, and make both scientists put their hands up. After they've run off, blow up the computers with your ZMG 9mm. Go back to the area with the first scientist and blow up those computers. Climg up the stairs, and head for the door in the other side. Kill the guy, then open the doors. Kill the guy on the other side, then switch to your AR33. There are three soldiers on this winding path, so snipe them with the AR33. Once you reach two doors, switch to your ZMG and fire some shots at the doors. Men will come out, so shoot them as they come. Then, enter. Kill any stragglers, then place two timed mines on the boxes. Blow up the boxes to get ammo. Open the next set of doors, and kill the guys there. More men should come running, so kill them too. Walk along the top path, sniping people with your AR33 as you go. Once you see another set of doors, kill the men guarding it, then shoot the black glass panels. Men should come out of the doors. One will have an RCP-90! Take the RCP-90, and clear out the bottom path. Then, go to the secret area at the end of the bottom path. Place a timed mine on the middle box, and ammo galore! Blast the lockers, and enter the secret path. At the end of the path are more lockers. Blow them up, and more will come through. Once the men stop coming, step out into the room. Aim high and too the left, and blast the lockers. This will cause men to run down the stairs, where you can easily pick them off. Then, blow up the computers. Walk up the stairs, but be careful, an automated gun is at the top. Blow it up, and kill the remaining guys. Now, exit through the double doors, and take the path back to where you shot the glass panels. Enter the room, and head straight for the left corner. Kill the guy in the right corner, and the guy across the room. Switch to your ZMG 9mm. Carefully kill the guys in the center. Shoot at there chests one shot at a time. Any missed shots will blow up the barrels behind you! Once you've killed all the guys, use the radio to contact Jack Wade. Get the scientists to put there, arms up, then let them run out of the room. Back up, and fire at the barrels. KA-BOOM! Now, open the blast door. Kill the guys inside, then open the blast door on the left. Kill the two guys, then switch to your AR33. This is the hardest part of the level. Open both doors, but then hide behind the wall. Inch your way out, and you'll see an automated gun. Aim and blast it. Inch forward a little more. You'll see Alec Trevelyan, and an automated gun above his head. Blast this gun, then duck, and run at Alec firing. He'll run off, but follow him. Kill any guys in the next room, then enter the elevator. Time for the final showdown....
