Doom Must Fall

Doom Must Fall (dmf-sp.wad) is a single-level total conversion, originally designed by Mackey "Avatar" McCandlish and released in 1995 as part of a deathmatch episode, in which it was also known as Kreissack's Fortress. It was extracted and restructured for source ports in 2000 by Sparky of KISS Software. It includes a DeHackEd file (dmf-sp.deh) which modifies most of the enemies and weapons.

Secrets

 * 1) The area east of the start has two sections of wall that have a 'traditional' texture, both of which mark secret doors.  The northern one leads to a shotgun and a health or armor pickup. (sector 441)
 * 2) The southern secret door (see #1) leads to two boxes of charges. (sector 456)
 * 3) The sector east of the blue key in front of the switch that opens the door to the area north of the blue door counts as a secret and is impossible to miss. (sector 284)
 * 4) Entering the room east of the blue key from the north opens up a door to the north (to the north-east of the rooms with the switches) leading to a super armor upgrade, a stamina jolt, a light amplification upgrade, and an invulnerability. There is also a teleporter here to near the start. (sector 270)
 * 5) The room east of the blue key has four ledges, one of which contains a super ammo booster.  This ledge lowers on pressing, revealing access to a room with a super ammo booster, a health or armor pickup, a personal cloak upgrade, and a berserk.  There is a switch here which opens up a secret passage in the room with the mine launcher in the north-west.  This passage leads to some ammo, a stamina jolt, and a super armor upgrade.  There are two secrets here. (sector 120)
 * 6) See #5. (sector 119)

Bugs
On easy and medium skills it may not be possible to obtain 100% items as there are some health bonuses near the start that it is possible to destroy by shooting before picking them up.

On medium and hard skills there is a lost soul (thing 73) that is on a ledge that is too high for it to be alerted or shot at, thus making 100% kills impossible on these skills.

In order to exit the level, it is necessary to press 'use' on linedef 2002 in order to lower sector 472 to the floor, allowing the exit line to be crossed. However, sector 472 does not lower on pressing, thus seemingly making it impossible to exit the level.
