Part 13

Take supplies and approach the turret. A massive horde of Kleers and Minor Mechs will attack. Support the turret with rockets and C4. Major Mechs will join; use the Devastator to eliminate them, then return to the Kleers. Once the fighting subsides, use the turret to claim the minigun.

Head forward, collecting health, armor, and minigun ammo. Continue and you'll be attacked by Rocketeers and Scrapjacks. Use the minigun to defeat them. Take the armor and minigun ammo to the left and proceed to the gate. Use the secret keys to open it for secret minigun ammo (5/10).

Upon exiting, go left, collecting health, armor, and minigun ammo while eliminating enemies. The area is well-stocked with minigun ammo.

Continue forward; a wave of Kleers will attack. Use the minigun for maximum damage.

As you approach the next gate, you'll face Major Mechs, Scrapjacks, and Rocketeers. After defeating them, go to the gate, turn left, and kill the Scrapjack. Go to where the Scrapjack was, kill another, and take the key inside the shack. Collect health and shells in the central building. In the back right corner, kill a Gnaar and take minigun ammo. Shoot the back right wall with rockets for secret rockets (6/10). As you leave, four Antaresian Juveniles will attack; kill them.

Go through the gate and kill Cave Demons. The central building contains health, armor, shotgun shells, and a tablet.

Pass through one of the gates and take the armor and C4 on the right. Go left to collect ammo, armor, and health.

Enter the next yard and kill Soldiers. Continue blasting Soldiers and a Scrapjack. Go right to grab pills, armor, and C4.

Proceed up the left side of the yard, watch out for Soldiers and Scrapjacks. In the back left corner, kill more Soldiers and collect health, assault rifle ammo, and armor. Get the key in the shack and go to the stone to its left. Jump from here to get secret health on the roof (7/10).

Approach the exit gate. You'll be ambushed by Soldiers, a Scrapjack, and a Witch-Bride. Defeat them, collect supplies, and go through the gate.

To the right are health and C4. Go further right; behind a corner are secret cannonballs (8/10). Go left; behind a broken pillar are secret armor (9/10). Take ammo and armor and head down the final corridor.

You'll be attacked by Beheaded Rocketeers, Kamikazes, and Scrapjacks. After they're dead, Bulls will attack, followed by Kleers. Retreat behind the gate if necessary.

After defeating the Kleers, grab remaining supplies and advance, taking minigun ammo and Devastator shells. Health and armor are on the backsides of statues. Go to the gate. Around the left corner are secret Devastator shells (10/10). Go through the gate to end the level.

The Power of The Underworld: Head forward and read the tablet to the right of the stairs. Go around the row of statues to find health, armor, shells, assault rifle ammo, and rockets. Continue to the pit; there's nothing there. Go to the other side and step outside. Turn right and follow the wall to the corner for secret health (1/9).

Start killing Soldiers and Kamikazes. Gnaars and Kleers will also appear. Once they're dead, grab supplies and finish off stragglers.

Continue forward to trigger more Soldiers, Kamikazes, and 2 Adult Arachnoids. After they're dead, proceed. You'll find a health kit on a wall you can't reach. Kill the Kleer inside its building. Go to the wall across from the entrance, turn left, climb a wall, jump a gap, climb a second and third wall to reach secret health (2/9).

Continue forward, looking for a modern shack to the left. Go there and take the armor to its right and the health and key inside.

Exit and head to the temple on your right. Read the tablet to the right of the door. Enter and take the ammo, health, armor, and Horus seal.

Upon exiting, kill the few Kleers and Arachnoid Hatchlings.

Go to the edge of the big pit in the far right corner. Eliminate visible Gnaars, Kleers, and Arachnoid Hatchlings. Hop down and finish off any remaining enemies. Explore rooms in the walls for Devastator shells and armor. Skip the one with the tunnel for now.

Go to the center and read the tablet. Enter and while the Osiris seal is acquired, jump into the small room behind the statue for secret armor (3/9). Take the seal. Kill Kleers and Arachnoid Hatchlings as you leave.

Return to the room with the tunnel in the back, take shotgun shells, armor, and Devastator shells. Go through the tunnel, killing a Kleer. Take health and armor and climb the ramp.
