Decade

Decade is a map designed by Russell Pearson and released in 2004. It requires a ZDoom-compatible port. It uses the music track "Sinister" by Robert Prince. There is no par time.

The level was constructed as a homage to celebrate that 2004 was Doom's tenth year. It is a "new school" map (using detailed architecture, ACS and other port features) constructed to be evocative of iconic areas from both Doom and Doom II.

It is built for single player only: there are no cooperative or deathmatch player starts. The level received one of the 11th Annual Cacowards at Doomworld.

In 2019, Pearson released, replacing the DeHackEd with Decorate and adding features from GZDoom's OpenGL renderer such as Dynamic Lights and Brightmaps. The remaster also included a new mode named "Clucking Hell".

Secrets

 * 1) At the start, open the door ahead and enter the hall. At the first bend, press on the wall with the vent to find a hidden switch, which raises the lift at the starting point. Get on quickly, if you miss it, jump onto the crates and onto the one with the switch at the top to lower the lift. The outer walkway above contains health bonuses, armor bonuses, and at the end of each path, imps guarding several other supplies. (sector 686)
 * 2) In the hallway north of the C-shaped room, head to the north end to open several doors. Backtrack to the south end of the hallway to discover two side rooms are open. Clear out the enemies and enter the room on the left. Jump onto the crates on the north side, then to the crate that has the switch at the top. Stepping on it reveals a rocket launcher in the opposite room. (sector 1259)
 * 3) After using the switch southwest of the circular walkway over nukage, drop back onto the walkway to release several lost souls. Now get back onto the high walkway east of the circular walkway and time a jump so that you drop down from the southeast edge onto the floor below where the two lost souls came from. Inside this secret area is a shootable switch, a soul sphere, a box of shotgun shells, two Hell knights, and two armor bonuses. (sector 1013)
 * 4) Enter the blocky area that is northwest of the C-shaped room and turn northwest when you enter. Note the walls in each compartment have UAC logos on them. The one northwest from where you enter has a large UAC logo. Shoot it to open the compartment further and collect a backpack and two health bonuses. (sector 515)
 * 5) From the previous compartment, head north to the second-to-last compartment on the left side. Shoot the wall here to get a backpack and two health bonuses. (sector 518)
 * 6) To the southeast from the previous compartment, shoot this wall to get a backpack and two armor bonuses. (sector 505)
 * 7) From the previous compartment, go a bit northeast and turn to the west, shooting the wall to find a backpack and two armor bonuses. (sector 506)
 * 8) To the northeast from the previous compartment, shoot this wall to get a backpack and two health bonuses. (sector 512)
 * 9) In the room north of the hallway that is north of the C-shaped room, go towards the megaarmor and notice the barrel stuck within the crates. Shoot this barrel to cause a major explosion, and get back as far from it as you can, because rockets will be flying in all directions. When it is over, examine the rubble to find a soul sphere at the west end. (sector 2026)
 * 10) The teleporter that led to the northwestern arena can be used again, but this time, it will take you to a secret teleporter where you can pick up some minor supplies. (sector 1221)
 * 11) In the previous secret, take the next teleporter on the platform and then go towards the open grating on the left wall. A hidden teleporter is behind this grating. Taking it leads to the north end of the area where you can pick up some health and armor bonuses behind some compartments. (sector 1958)
