Map08: 4 Sides of Death (Prodoomer)

This is the first major boss map of Prodoomer, and the final stage of Chapter I. The official name of this map is 4 Sides of Death, but the game will refer to it as Spiderdemon 666 when you unlock it. If you revisit boss levels, you can refight the boss.

Each of the three keys needed to unlock the boss room are guarded by devious ambushes and traps, but there are ways to circumvent them.
 * Get the blue key first so that you can open the blue bars covering the niche with the computer map.  The four arachnotrons that ambush you when you grab the blue key can be killed preemptively with the Telekinesis or Rays spells.
 * Get the red key second so you can acquire the computer map.  Before you pick up the red key, drop Sandbags at the entrance to the room with the blue bars to distract the enemies that will teleport in.
 * With the computer map, finding the correct path to the yellow key is much easier.  It's in the guarded area in the northeast corner of the nukage maze.  Rad suits are limited, so jump repeatedly to avoid contact with the nukage, keep your armor topped off with the Green Armor spell, and save the barrels so you can stand on them.

Average Payout: 1,500 credits

Secrets
1. When you take the east door leading to the nukage maze, check the south wall on the southeast platform for a secret door. Be prepared to fight off the enemy inside.

2. In the western sector, you may have noticed a switch inside the caged area from where several enemies were shooting at you. Check the southern staircase to find a fake wall that will let you inside. Press the switch and go back outside to the room with the health bonuses. Above the computer console to the right is the secret area that just opened up, but you'll have to place sandbags to reach it.

3. Entering secret #2 will lower a barrier behind a false wall in the red key room, located high up on the west side. If you look very carefully, you'll notice a shootable switch in the back. This gives you access to the barred-off room.

Rings
17 In the starting room, in the northeast corner, is a nukage falls. Rocket jump up there to get a ring.

Boss Strategy
Cast your Sandbags spell as far ahead of you as possible before entering the boss room. When the Spiderdemon attacks, run around behind it and shoot it in the back with your Super Shotgun while it's distracted. While most players will instinctively try to keep their distance and strafe around behind the pillars on the periphery, the Spiderdemon has a deadly seeking attack designed to counter this strategy, which it only uses when the player is too far away. Therefore it's best to stay relatively close. The boss is worth 433 XP when killed.
