UAC Invasion: The Supply Depot

UAC Invasion: The Supply Depot is a single-level PWAD for Doom II and the ZDoom source port. It was released in September 2018 by DooMknight after an 11-year development process, and includes a custom music track by Andrew G. Sega, along with title and intermission tracks. It was one of the winners of the 2018 Cacowards.

UAC Invasion: The Supply Depot includes a DECORATE lump with associated sprites that define several new monsters and a large array of custom objects.

Secrets

 * 1) Enter the room east of the start and get the berserk pack on the conveyor. (sector 4203)
 * 2) Enter the maintenance area and use the switch, then head right and up. Open the east door to an outside area with crates, then get on the conveyor to the south and go through the vines to find a super shotgun, shotgun shells, and a stimpack. (sector 4561)
 * 3) In the hall east of the outside area with water and a super shotgun, open the damaged wall to the east to find a backpack, a box of shotgun shells, and a medikit. (sector 913)
 * 4) Head south and east from Secret #3 and open the door. Open the north wall for a soul sphere. (sector 3645)
 * 5) Open the door east of Secret #4, then two doors to the north. Go on the steps and open the north wall with the electricity symbol to find a megaarmor. (sector 7750)
 * 6) In the hall east of the cages and north of the large teleporter, there is a panel on the east wall that is open, revealing a switch. Shoot it, then head north, open the blue door, then head to the next door going south. Take the side path to find ammo, a megaarmor, and a medikit. (sector 1178)
 * 7) Head south of the yellow switch door and open the door there. In the room with the water and conveyor belt, follow the conveyor west and north, taking a lift up to some ammo. Open the door for a soul sphere. (sector 6985)
 * 8) In the brown area with the nukage, before the intersection, open the west terminal to find a plasma gun and energy cells. (sector 10809)
 * 9) North of the helipad, head northwest until the steps, then notice the switch to the left over the fence. Use it, then head back to the southeast and take the lower set of steps down. You will soon see an energy cell pack and a megasphere. (sector 6511)
 * 10) In the large field with the lowering soul sphere pillar, head north of the pillar to find a switch. Flip it and quickly run southeast to two lowered pillars that have a megaarmor and a backpack. Both pillars count as the same secret. (sector 3405)
 * 11) Enter the room northeast of the large field and use the northwest terminal to lower the two central ones, with a soul sphere and backpack. Both terminals count as the same secret. (sector 2873)
 * 12) After taking the long lift down to the easternmost area, head north in the large hall and open a wall to the right of a voltage sign on the west side to pick up a computer area map. (sector 8900)
 * 13) At the southeast end of the easternmost area is an area with water flowing and a bunch of crates. Climb the crates and fall on the other side to find a soul sphere. (sector 8437)
 * 14) At Secret #13, head southeast through the vines to find a switch. Flip it to unlock the bars in the nukage near the west side of the easternmost part of the map. (sector 8925)
 * 15) In the main hall east of the red key, take the steps up, then use the switch to the north. Go back down the steps and enter the room to the north. The ledge with the energy cells is a secret, and you can get on it by pressing on the northeast part of the ledge. (sector 7620)
 * 16) Use the red key switch at the easternmost end and take the lift up. At the top, open the door and look at the east wall. Shoot the red spot to open a nearby wall to find a blur artifact. (sector 9017)
 * 17) After you finish with the easternmost area, return to the brown area with nukage and take the steps to the southwest to find crates over nukage. Follow these crates over to the northwest crate which has a radiation suit. (sector 9115)
 * 18) In the courtyard below the blue key, take the south door. In this hall, use the terminal south of the west door to find a berserk pack. (sector 9852)
 * 19) Enter the vent near Secret #18, then head south, east, then south. Shoot the switch in the distance to raise the floor and head further south until you can head east to find ammo, medikits, a megaarmor, BFG9000. (sector 9614)
 * 20) In the room with the blue floor southwest of the vents, head to the center and use the terminal with the keyboard on it to lower the south wall with a megasphere and a computer area map. (sector 9693)
 * 21) In the hall where Secret #3 is, open the north door to head outside. Directly to the left of the door is a switch to use. After using it, head to the courtyard below the key, head north to the water, then head east when you can and climb the steps to get a BFG9000 and energy cell packs. (sector 5586)
 * 22) At the northernmost end with the spider mastermind, look to the northwest and shoot the green switch, which lowers the megaarmor near the waterfall. (sector 6745)
 * 23) At the west end, open the east door to the room with the imps signs, then open the next door and enter the cave afterwards. Climb the steps, then go southwest through the vines to find partial invisibility, medikits, a box of rockets, and an energy cell pack. (sector 7404)
 * 24) Head back and then take the south door. Follow the path to a room, then flip the switch to open the east door. Open the wall directly to the east of that door to pick up a soul sphere. (sector 10091)
 * 25) At the northwest tower in the westernmost area, look out the east window and shoot the switch, which will lower the nearby platform with the soul sphere. (sector 10631)

Bugs
A pool of blood (Thing 1753) has no flags set for any of the three difficulty classes, so it does not actually appear in the level.

There is an imp (Thing 3471) in the toxic flooded area that never attacks the player.

A health bonus (Thing 5077) is located in a normally inaccessible part of the level, making it extremely difficult (but not impossible in GZDoom with rocket jumping in hardware rendering mode) to obtain 100% items without cheating.

It is possible to get stuck in the area where the battle with the spiderdemon and arachnotrons takes place by entering it again, since the trigger to close the entrance is activated by multiple linedefs just past it, and reopening it from the inside requires killing the spiderdemon, which obviously cannot be done more than once.
