AREA 51
ESCAPE
Difficulty: Agent
Target Time: 3:50
Cheat: Invincibility
Start off by running through the first two doors, and when you get into the big hall, start speed strafing. Go to the end, and go through the door then turn right. Go through the next door, and kill the scientist in front of you. Now run straight through the brown door, and turn left down the ramp. When you get to the bottom, you have to back into the door to open it. Place Elvis in the room, then head back up the ramp, and kill the scientist at the top. When you get to the top, turn right and go to the back of the room. Now you will see a ramp that goes down. Open the door at the bottom, and turn right. Kill the two guards, then head out the door to the left. Kill the guard here, then head out to the catwalks, and kill the two guards here. Now head to the end, and go through the door.
You will see Jonathan here, so talk to him, and run back to the other end of the catwalks. Open the door, and place one grenade from your superdragon in the middle of the group of guards. Now wait for Jonathan to catch up, and he will begin to plant a bomb against the wall. Cover him while he is working, then when he backs away, shoot a grenade where he was working. This will blow up the bomb a few seconds early. Now run down the ramp, and go through the door at the bottom. Now there will be a cutscene with elvis.
Skip it, then go back out the door, and look up the ramp that you came down. Make sure that there are no guards here, and of there are, kill them. Now head towards the alien spacecraft, and wait for Elvis and Jonathan to come. When the conversation starts, head up the ramp and then turn around. Go to the end, and kill the guard on the right. Now go stand next to the console he was standing by. Just wait here until the fast music starts. When it starts, activate the console, then run and activate the other one. But make sure that you wait for the fast music to start, otherwise you will have to get on the hoverbike and exit. This will take an extra minute, causing you to miss the target time.
