Part 14

Begin by taking the right path and following the sewer. In a down-sloping, lighted room, eliminate enemies, especially electric fish, before swimming down. Follow the sewer, using the Grenade Launcher for the brutal fish. The exit is to the right.

In Metropolis (Level 9), kill monsters, climb the ramp, and follow the perimeter of the square. After collecting items, proceed to the next courtyard. Use the rocket launcher for enemies like Harpies. After clearing enemies, items generate in the center. Collect them and enter the building.

To open the exit door in Metropolis, collect four scarabs. The first is forward from the entrance. The second is to the east, slightly right from the entrance. The third is almost directly opposite the second. The fourth is to the east, entered from the south. Enemies include Rocketeers and Grunts. Exit to the north.

Proceed through a long alleyway, being wary of Reptilioids. When you reach a pit, jump on charging Bulls to cross. Continue through scattered Bulls and Skeletons, then face a large mob of Skeletons. Use the Minigun and Rockets to control them.

In the next courtyard, face multiple enemy waves:

Wave 1: Kamikazes from all directions (approx. 3 minutes). Use Tommygun or Colts. Items spawn in the center afterward.

Wave 2: Harpies from north, then west, east, and south. Group them and use rockets.

Wave 3: Harpies from the south. Items spawn in the center afterward.

Wave 4: Bulls from the north. Circle around and collect the backpack in the center.

Wave 5: Skeletons from the north, commanded by a Bio-Mechanoid. Use Rockets.

Wave 6: Skeletons from the north.

Wave 7: Skeletons from the north, commanded by a Bio-Mechanoid.

Wave 8: Skeletons from the north.

Wave 9: Skeletons from the north, commanded by a Bio-Mechanoid. The exit door opens after this wave.

In Alley of the Sphinxes (Level 10), you start with no weapons. Collect initial items and use the Shotgun. Deal with Knarrs and Grunts. More Grunts and Kamikazes spawn with the next items. A Werebull spawns with the following items; let it run over Grunts. A Bio-Mechanoid and allies spawn next.

Acquire the Cannon, the most powerful weapon. Use it to hit a Bull so it rolls into the Mechanoid behind it. Conserve Cannonballs.

In the next courtyard, face more waves:

Wave One: Kamikazes and Skeletons. Use pistols and Shotgun. A heart and ammo spawn after.

Wave Two: Bulls from all directions. A door to the north opens afterward; collect items inside.

Enter another huge courtyard with four platforms for runes. Place a rune in each corner. Each placement spawns assorted enemies, including Bio-Mechanoids, Knarrs, Grunts, Reptilioids, and Kamikazes.

After placing all four runes, collect items in the center. A Lava Golem appears. Use the Cannon to defeat it.

Deal with the mini-Lava Golems using the Lasergun.

Go through the final door to finish the level.
