DOOM + DOOM II Update 2 Release Notes (28th January 2025)

Update 2 adds Multiplayer Mod support for DOOM + DOOM II and game improvements/fixes!

Improvements

All Platforms

Multiplayer Mods

  • Hosts need to activate the mod before entering the multiplayer menu
  • Players will need to subscribe to the same mod before joining a match
  • We recommend using room codes to join modified matches
  • Mods must be authored with Vanilla DOOM, DeHackEd, MBF21 or BOOM to be compatible

General

  • Resolved an issue in which some red doors did not display as red on the automap
  • Fixed multiple crashes reported by the community when loading game saves
  • Improved text line wrapping legibility for mod descriptions in Asian languages
  • Removed map prefix from intermission screen to be consistent with original game behavior

Multiplayer

  • Items can now be picked up by all players in co-op mission play
  • Added spectator mode when players are dead and waiting to respawn in co-op mission play (it can also be initiated manually from the scoreboard button)
  • Fixed an issue in which disabling the crosshair would also turn off player name and co-op respawn text display
  • There are now more than 4 player colors available in game and on scoreboards
  • Resolved an issue in which players would lose weapons when respawning in co-op using modern rules

For Mod Creators on PC

  • Mod screenshots with spaces and other non-alphanumeric characters in their file names will now upload correctly in most cases

Mod Compatibility Updates

  • MBF21 instant kill sectors were incorrectly killing non-enemy actors
  • MBF21 instant kill sectors will fire immediately when a monster enters them, instead of waiting
  • BOOM and MBF21 effects that kill monsters will deal 1 million damage instead of 10000 damage in order to fix mods that used monsters with high HP values to create an invulnerable enemy
  • BOOM generic floor actions were not selecting the right neighbor when finding which sector ceiling or floor height they needed to move to
  • Players can hurt and shoot projectiles at their own voodoo dolls (aka player model / clone), to be consistent with the original game
  • ENTERPIC in UMAPINFO is correctly shown for the map you are entering instead of the map you just left
  • DeHackEd strings for BOOM keys can now be replaced through DEH patches
  • BOOM line action 242 (Deep water) will now transfer ceiling and floor lighting
  • Now avoids crashing for invalid sized demos when playing the demoloop
  • Maps using DMAPINFO will print the map name on automap, level select, and savegames
  • Changing DeHackEd ammo type will now actually change the ammo type
  • Fixed Berzerk Factor not calculating correctly in the A_WeaponMeleeAttack MBF21 codepointer
  • Fixed BTSX Episode 1 and Episode 2 demo playback not rendering fullscreen
  • Mods that override DOOM (1993) Episodes 1-3 will use the correct intermission screen
  • MBF21 A_Lower codepoint now checks for an invalid weapon before changing weapons if out of ammo
