MAP20: Castle Bloodletting (NOVA: The Birth)

MAP20: Castle Bloodletting is the twentieth map of NOVA: The Birth. It was designed by Collin Pierce (Arjak) and uses an untitled music track by nub_hat.

Secrets

 * 1) Exit the cave at the start to the outside, with two big trees nearby. Approach the tree to the right, then return to the cavern as quickly as you can and to the brighter section. Inside is an invulnerability (only on Hey, Not Too Rough or lower), partial invisibility, and a backpack. (sector 20)
 * 2) Inside the castle, take the left door, then go up and take the next door. Turn left and open the first door you see to the room with the window. From there, you can make an angled jump to reach the crate with the rocket launcher outside. (sector 26)
 * 3) In the red key room, first open the south door, then walk between the southernmost column and the south wall. When you do so, quickly run through the open door and east, until you reach a compartment that had chaingunners before (you probably have not opened this compartment already, but it will be opened as you approach it, in that case, kill the chaingunners first). The wall in this compartment will be open briefly, leading outside. Enter the outside area to find some ammo and a plasma gun. (sector 103)
 * 4) In the red key room, first open the north door, then walk between the northernmost column and the north wall. When you do so, quickly run through the open door and then down the steps. When you see the light, turn left to the open compartment to find a soul sphere and a backpack. (sector 162)
 * 5) In the blue key room, use the lift in the southeast corner to go up to the wooden crate. Sidle along the east wall to the northeast crate and open the wall in the northeast corner to collect a computer area map. (sector 278)
 * 6) The yellow key is directly behind a throne. If you step onto this throne however, you will briefly unlock a teleporter in the previous hall. Run back there as quickly as you can and enter the teleporter in the middle to be transported onto a high ledge in the previous courtyard, where you can get an energy cell pack and a BFG9000. (sector 282)

Bugs
A number of multiplayer-only items have no flags set for any of the three difficulty classes, so they do not actually appear in the level: a chainsaw (Thing 663), a backpack (664), a super shotgun (668), a box of shotgun shells (669), and an armor (671). Additionally, a deathmatch start (656) has no skill flags, but because of special handling in the engine, it functions normally.
