MAP STATS: (47)

Head forward and keep to the left tunnel. Near concrete barriers, find a Shotgun and Railgun.

When shots begin, take cover behind the divider between tunnels and engage the five Pigcops below (two Pistol, one Shotgun, two Berserks).

After clearing the Pigcops, proceed through the small office between tunnels.

Wave 1: Pistol Pigcop, Shotgun Pigcop.

Wave 2: Three Assault Trooper Captains.

Wave 3: Pistol Pigcop, Shotgun Pigcop, Assault Trooper Captain. As Wave Three arrives, an RPG Duke Bot and a Ripper Duke Bot will approach from behind; eliminate them as well.

Use your current weapons to defeat the first wave, then quickly jump on the turret. If fast enough, you can prevent subsequent waves from leaving their cover behind the car at the end of the corridor. Aiming at the car can also explode Pigcops, but be cautious of friendly fire from your companions.

After passing the area where you fought aliens and bots, look left for a large hole in the wall. Enter it and open the door to the storage room. Inside, find a Freeze Ray, and three EDF crates containing Steroids, a Pipe Bomb, and two Laser Trip Mines.

Exit the storage room and go left towards a rolled-over truck trailer. Carefully walk around the edge and inside. You'll find two EDF crates: one with a Pipe Bomb, and another with a Holoduke and another Pipe Bomb.

Exit the truck and climb the ramp. You can backtrack to pick up the Shotgun and Railgun if desired.

Near the ramp, an EDF corpse with a Ripper can be found. Continue forward, and a Ripper Duke Bot will open the door to your right.

Enter this room and observe an RPG Duke Clone and a Ripper Duke Clone engaging two Assault Trooper Captains. This is a good opportunity to use Steroids. You can either let them fight and then attack the winner, or join the fray. In the room to the right of this fight, find two EDF crates in the far corner. One contains a Pipe Bomb and a Laser Trip Mine; the other contains a Laser Trip Mine.

A Shotgun Pigcop will appear; eliminate it. In this room, the third locker from the left contains a Beer.

Exit through the new door back into the tunnel. The small security booth offers the best cover for the upcoming shootout. The Ripper or Rail Gun are most effective from this position. A new Rail Gun is located in front of the booth.

Two Enforcers with Shields will advance from the far end of the tunnel. Use the Rail Gun or Pipe Bombs to destroy their shields, then attack with other weapons. An Expander is also located at the far end of the tunnel by a corpse.

After the Enforcers are defeated, or if you approach the large door at the end of the tunnel, an Assault Commander will appear. Use all available weapons, including Enforcer Guns and the Rail Gun, to defeat it. The Expander can slow it down significantly, making it easier to kill.

Following the fight, Graves will comment on the teleporter. Aliens will then begin destroying the tunnels. Dylan will attempt to open a roller door and will need your help. You can steal his Shotgun before the Strength Tap mini-game.

After winning the Strength Tap, you will enter the Magic School Bus.

Inside the bus, you will face three enemies: an RPG Duke Bot and two Ripper Duke Bots. Use the ramps to jump gaps and eliminate enemies until a cutscene triggers, ending the level.
