To defeat the Arnolds, stand in front of them and launch four rockets at each. Use a RATION (F3) if needed. After the fight, collect CARD 7.

Use CARD 2 (F3) to exit the room via the northeast door. Kill the guard and proceed east.

In the next room, kill the three guards. Call Jennifer (F4) at 120.48 to open the north door.

Enter the room and grab the COMPASS. Exit and return to the room where you fought the Arnolds.

Use CARD 5 (F3) to enter the southeast door. Kill the three guards inside and enter the west door.

Rescue the POW inside; he will tell you a COMPASS is needed for the SCORPION DESERT.

Exit the room and head right. Sneak past the sleeping guard between the crates and use CARD 5 (F3) to enter the door.

Get past the rolling pin and enter the elevator, watching out for the trap on the right. Take the elevator to the first floor basement.

Kill the dogs and exit the room. Schneider will warn you about gas. Use (F3) and enter the left door.

Equip your GAS MASK (F3) and follow the path to the trap room. Use CARD 6 (F3) to enter the south door.

Be careful in this dark area; Diane will call (F4) to warn you about pitfalls. Equip the FLASHLIGHT (F3).

Head down the left path. On the next screen, go left by the crates to avoid a trap, then quickly run down to the next screen to avoid a second trap.

On the next tricky screen, a trap is in the top center. Slowly walk towards it to activate, then step back. Another trap connects to the southeast. Move quickly to avoid it. Head down.

On the next screen, get to the south side of the north crates. The northeast corner of the left trap connects to the southwest corner of the crates. Avoid the traps to reach the south side of the crates.

Position yourself in front of the small crate on the right and head straight down to the next screen. Stay on the west side of the box on the right, head down and two steps right to avoid a trap. Proceed down and use CARD 1 (F3) to enter the door.

You are now in the first floor basement of BUILDING ONE. Kill the five attacking guard dogs and head south.

Kill the two more guard dogs and use CARD 6 (F3) to enter the east room.

Follow the east wall north until you reach the middle. Punch the north part of the east wall until you hear a tapping sound. Use a PLASTIC EXPLOSIVE (F2) to blow open the wall.

Inside, find and rescue Ellen Pettrovich. She reveals her father was forced to create Metal Gear and asks for your help.

Exit the confinement cells, staying on the wall. Use CARD 6 (F3) to exit through the south door.

Move through the room outside the confinement cell and the room where you fought Shoot Gunner.

In the spiral room, use CARD 4 (F3) to enter the south door and take the BODY ARMOR. Exit the room.

Head back to Dr. Pettrovich, either through the DESERT (using your MINE DETECTOR (F3) to avoid MINES) or back through the trap screens.

Upon reaching Dr. Pettrovich, he will reveal Metal Gear is in the 100th floor basement of BUILDING THREE and that you need to attach PLASTIC EXPLOSIVES to its feet in the order: R, R, L, R, L, L, R, L, L, R, R, L, R, L, R, R.

After the conversation, exit the room and take the elevator down to the first floor.

On the first floor, kill the two guards in the room with crates and exit.

Exit the next empty room via the west door and head north, killing the guards.
