Part 27

Pick up armor in the corner. As you exit, commandos will appear. Grab armor behind the building and ammo from the far corner while clearing remaining monsters and collecting souls.

In the next area, you'll face many sado commandos. Keep moving and use the chaingun or electrodriver. Grab stray souls with the Soul Catcher card. Find ammo and a rocket-launcher at the back. Once the outer area is clear, the building doors will open.

Inside the building, grab ammo and deal with commandos. Drop through the broken window on the upper floor to reach the checkpoint.

There's a secret area with mega ammo on a half roof; return later.

You'll approach an area suitable for Demon Morph.

[CHECKPOINT 1] The large door behind you will close. You must complete the map to reopen it. To access secrets, you may need to return to the level's start.

Boxes ahead will release commandos, with more approaching from the right. Run, jump, and shotgun while collecting ammo (including behind the boxes) and use Demon Morph.

Reach the far end and eliminate commandos jumping over the wall. If you've managed well, you can use Demon Morph again as the last commandos die. Head into the next area and use it, looking for maso commandos at the far end.

[SECRET 1] After clearing minions, look under escalators for ammo. In the back of the train on the right, find a secret area with two holy items. Look at the top of the third tank in the left row; shoot it with a rocket to make it fall off. Find a broken wall between the third and fourth tanks. Jump up pipes and onto the fourth tank (avoiding fire), then to the wall, and into the third tank's bowl for a holy item.

To access a later area, move a yellow and black striped hook to the door that closed behind you.

Pick up ammo boxes around the oil tanks and proceed to the next checkpoint.

[CHECKPOINT 2] Avoid the crates ahead as they will explode. Skeleton soldiers will emerge; use rocket-launchers to defeat them and collect souls. Go right to the two large gas tanks. Snipe commandos from the top and eliminate the commando on the nearby building's stairs.

[SECRET 2] To reach heavy armor on a cylindrical tank, jump up three pipes at the back, then up the tank's curve. Twist and jump to reach the top.

A maso commando is in the doorway behind this tank. Stake him and avoid his soul if close to another Morph. Clear the building without picking up souls, then grab ammo and armor. Hit the checkpoint. This ignites the furnace in the room's center.

[CHECKPOINT 3] Go to the back of this area and shoot the flaming barrel beside the tall gas canisters to destroy a large group of soldiers. This also opens the main building.
