Map12: Raynor Truth (Prodoomer)

Raynor Truth is a large base complex with several dangerous ambushes, but also the most treasure of any map thus far. There are usually ways to mitigate the ambushes, such as by using summons, but you may still take some damage if you can't react quickly enough.

Average Payout: 4,600 credits

Secrets
1. In the small blue room right after the water tunnels, but before the control room with zombies, crouch and search the southwest corner for a secret door.

2. In the eastern part of the map is a switch guarded by revenants and imps, from where you can see a large outdoor area. Search the south wall behind the revenant for a hidden corridor leading to a switch. This will open the south door back out in the hallway. Be warned that a couple of kamikazes guard this path, but it will take you outside where you can get some items.

3. After you ascend the stone pillars in the cave leading to the building with the yellow key, but before you enter the building itself, check the north wall at the topmost level of the cave. There is a secret with some ammo.

While not a secret, there are boxes of rockets on the wings of the ship at the end.

Rings
26 In the watery room guarded by lost souls there are two narrow corridors to the east and north. Take the northern one and rocket jump as need be so that you can follow it to the end. You'll find a ring, as well as a good vantage point to snipe the enemies in the room without exposing yourself to the kamikazes.

27 In the watery area to the east of where you start, check the southwest corner for this ring.

Boss Strategy
The Mechanical Monstrosity moves slowly, but will rapid fire incendiary and heat seeking missiles. Cast Sandbags immediately, stay behind cover using the four pillars, and use area effect attacks like Dragonfire that can hit the boss around the corners. There is a ton of ammo lying around, but if you want to bring a quick end to the fight, summon all your allies beforehand and let them handle most of it. You get 500 XP for defeating the boss.
