Insanity Deathmatch

Insanity Deathmatch, also known as InsanityDM or IDM, is a PK3 file for Deathmatch, Last Man Standing and Capture the Flag developed by Kaapeli47. It was released on November 7, 2021 for Zandronum, after multiple beta releases throughout the year, and version 1.0 in August 31. The mod works in the Instagib and Buckshot modifiers of Zandronum, and it also comes with its own additional game modifiers, such as weapon modifiers similar to Instagib and Buckshot, and modifiers that change gameplay directly.

Insanity Deathmatch comes in two editions. The normal edition, simply called 'Insanity Deathmatch', has advanced modifications to player properties with additional player sounds and death animations. The other edition, called Insanity Deathmatch: Skinnable Edition, has classic player behavior without advanced additions, enabling compatibility for custom Zandronum player skins.

Insanity Deathmatch is compatible on any map that only has things from Doom2.wad. In these maps, the mod replaces items like weapons, health, armor and powerups of Doom II with randomized spawner actors that spawn random weapons and items. In addition, Insanity Deathmatch can be used as a resource for mapping with Ultimate Doom Builder to design maps specifically for the mod. As a mapping resource, Insanity Deathmatch allows placement of individual things from the mod, although placing the random spawners is still possible.

The mod is an affiliated Doom project in Hellforge Studios, and it received one of the 2021 Cacowards in the Multiplayer category.
