About this mod Author’s original text

Unlimited Upgrades

Unlimited Upgrades lifts the default 2-slot limit on player ships in House of the Dying Sun, allowing you to equip as many Field Upgrades (modifiers) as you want on any ship in your fleet!

Features

  • No Upgrade Limits: Equip 3, 5, 10, or all available upgrades simultaneously on your Interceptors, Destroyers, and Capital ships.
  • Checklist Toggle Selection: Upgrades in the selection grid act as toggles—click an unequipped modifier to equip it, or click an equipped modifier to unequip/remove it. No tedious slot swapping required!
  • Smooth Slot Scrolling: The ship overview hangar UI uses a responsive sliding window:
  • Mouse Wheel: Hover your cursor over the modifier slots and scroll up or down.
  • Keyboard / Controller: Navigate with Arrow Keys / WASD / Controller D-pad; the slots auto-scroll when reaching the edge.
  • Quick Add Slot: An empty slot is always appended to the end of the scroll list so you can easily add new upgrades.
  • Capital Ship Crash Safeguards: Built-in compatibility filters automatically prevent invalid fighter-only modifiers from being attached to capital ships, ensuring zero mission crashes or glitches.
  • Save & Load Compatible: Seamlessly integrates with the game's save system and the GameSaves 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.
