MAP31: Meat (Doom Zero)

MAP31: Meat is the first secret map of Doom Zero. It was designed by Christopher Golden (DASI-I).

Secrets

 * 1) Cross the zigzag bridge in the middle of the map and use the south wall where a pool of blood is. You can find a megaarmor at the end of the passage. (sector 0)
 * 2) Cross the zigzag bridge in the middle of the map and approach the yellow door, which will lower a platform near the zigzag bridge allowing access to the yellow key. Go back to the start of the zigzag bridge which will cause a lift to lower. This lift is north of where the yellow key is, and it takes you up to energy cells, a box of rockets, and armor bonuses. (sector 151)
 * 3) In the area that looks like Entryway's big room, use the bloodfall to the south as a lift to get up, then go through the bloodfall to the south to find a switch. This will open a wall at the northeast end of the room, leading outside to a backpack and energy cells. (sector 83)
 * 4) In the area that looks like Entryway's big room, use the bloodfall to the south as a lift to get up, then you can jump north to the plasma gun. (sector 86)
 * 5) In the area that looks like Entryway's big room, go through the bloodfall to the north to get a box of rockets. (sector 94)
 * 6) In the area that looks like Entryway's big room, you can use the meat to get onto the platform with the soul sphere. (sector 106)
 * 7) Stepping on Secret #4 opens a room in the hall you came from. Go back west and north to find rockets and a rocket launcher. (sector 108)
 * 8) When you teleport to the area that looks like Quake's first level, get on the ledge to your right and shoot the east wall to pick up an energy cell pack. (sector 192)
 * 9) Use the wall behind the blue key and go across to the next lift to get a megasphere. (sector 325)
 * 10) Get the blue key, then return to the Entryway section of the map. If you have not done so already, shoot and use the wall behind the exit teleporter, then go to the section that looks like Entryway's beginning. Use the lift to go up, then open the blue door you find to remove the fence. Follow the path to reach the secret exit. (sector 77)
