Map09: Communication Base (Prodoomer)

This is a heavily defended base with a lot of free roaming enemies that can easily swarm you if you're not careful. There will be a lot of long range combat, so try not to waste pistol ammo. You can thin out some of the zombies by using Telekinesis through transparent glass to push them into each other, starting an infight.

Be wary of the new enemy type found perched on platforms above the lava pit to the north, as it fires a homing explosive that can chase you around corners and kill you almost instantly. The best way to avoid it is to hide behind cover partially exposed so the projectile flies straight at you and hits the cover.

Average Payout: 1,800 credits

Secrets
1. From the central area, the second passage to the west leads to one of the switch rooms you need to clear out. There are four columns in both the top and bottom paths. The second pillar on the bottom path can be lowered if you activate its southern face.

2. In the fourth passage on the east side, check the columns in the middle path this time. The first one on your left can be lowered.

4. Between the second and third passages to the west is a grayish-black panel. To open it, stand at the top of the nearby southern set of stairs that lead down into the lava river. Look up and to the left behind a hanging panel and shoot the green switch hidden there. Now you can gather the items.

4. To the east of the northern set of stairs that lead down into the central lava river, look for a similar grayish-black panel with a barrel in front of it. This wall can be lowered to reveal an outdoor secret area.

Rings
18 Take the fifth passage on the west and search behind the northern computers for a ring.

19 High above the central lava river, clearly visible, is one of the rings. The nearby jump pad does not reach high enough, so you will have to augment it with a mine jump. Position yourself dead center on the pad so that you're bouncing straight up and down, and set off the mine immediately after you touch the pad. This should net you the ring.

20 In the southeastern most switch room, accessible towards the end of the level, you can see a ring sitting atop the lava pillar. Sandbags will not work here, so you will have to jump to the ring and time a rocket jump to propel yourself back out before you hit the lava. You can also come back when you have the double jump if you need to try again.
