MAP19: The Spiral (Doom 64)

MAP19: The Spiral is the nineteenth map of Doom 64, designed by Tim Heydelaar. The level basically is killing loads of monsters in a large room which has a large staircase in it. If you look at the map from your automap, the level appears as a spiral. All you have to do is grab a red key and kill all the monsters that teleport in. Then you can go into the red door room and kill the last baron of hell and exit. It uses the music track "Collision Course".
