BiasedDoom 4.15.4

BiasedDoom 4.15.4

BiasedDoom 4.15.4 expands procedural missions into genuinely open combat
spaces, makes every generated vertical feature traversable, and completes the
player-skin, autoaim, and mugshot customization work.

Highlights

• Expanded the procedural map-size control into a continuous 1–20 slider. The
  upper range produces colossal deterministic routes and broad footprints.
• Raised the spatial baseline to 384-unit generator cells, 320–368-unit room
  interiors, 128-unit standard doors, and wider role-aware portals.
• Made ordinary rooms target at least two compatible cells and scale hubs,
  arenas, key rooms, and finales with map size and combat difficulty.
• Added reachable vertical combat: every raised ranged perch has 16-unit stair
  tiers, while optional reward lifts keep a permanent walkable bypass.
• Added switch-operated supply pavilions, key-triggered ambush reveals, clearer
  exit landmarks, keyed-border colors, outdoor spaces, and more varied room
  silhouettes.
• Centered texture phases per wall segment so opposite walls, doorway
  shoulders, chamfers, and accents remain symmetric and aligned.
• Restricted Cyberdemons to finales containing at least eight merged cells and
  removed the Spider Mastermind from generated finales.
• Kept player-selected skins active on replacement player classes and on the
  actual in-game actor, including third-person views and mods that mark a class
  as NoSkin.
• Added an explicit autoaim enable switch plus independent vertical and
  horizontal acquisition ranges.
• Added 0.25x–4x mugshot scaling, horizontal/vertical offsets, and reset controls
  for both the stock Doom ZScript HUD and legacy SBARINFO status bars.

Procedural Validation

The release candidate passed the structural matrix, fixed-seed determinism,
difficulty/finale-area balance, Ultimate Doom compatibility, menu integration,
runtime loading at sizes 1, 3, 5, and 20, and an 11-configuration seed stress
sweep. The fixed determinism case reproduced this SHA-256 hash:

See the procedural-generation research
paper for the representative
matrix and balance experiment.
