General Features

To Do:

  • Fix shrines. Either do not work and give no items or work without fail but give two items of the same rarity in a row (Drone scrappers too)
  • ~~Bosses killed need to multiply or add by number of bosses killed this stage so that each boss drops a different item.~~ (I think fixed but testing)
  • Naturally spawned boss enemy and scavs are unseeded
  • Drifter is unseeded

THIS MOD IMPLEMENTS CUSTOM SEED LOGIC DUE TO DIFFICULTIES WITH THE GAMES INTERNAL LOGIC, NORMAL RUNS WILL NOT HAVE A CORRESPONDING SEED FROM THIS MOD

Install & use Install: follow the bundled instructions

  1. Unzip the archive from playbuff and read the bundled readme / instructions first.
  2. Most mods rely on the game's mod loader — the usual route is a community mod manager (such as r2modman): pick this game, install, and it handles the loader and dependencies.
  3. For a manual install, put the mod files into the matching Mod / plugins folder inside the game directory.
  4. Launch the game to confirm it loaded; mods with listed dependencies need those installed as well.

Install locations vary a lot between mods — the bundled readme is the most reliable guide. If the mod depends on a loader such as ReturnOfModding, install it first as the readme describes.

Install these first, or the mod will not work:
