  • Difficulty Scaling: The difficulty timer runs faster (toggleable)
  • Teleporter: Teleporter charges faster
  • Player Boost: Players also receive a speed boost (0.875x the game rate) (toggleable)

Compatible with Eclipse

Configuration

Access settings via the menu bar: Tachyon

  • Custom Rate: Set the rate for Tachyon??? (only editable when using custom artifact)
  • Difficulty Scaling: Toggle accelerated difficulty and teleporter scaling(on by default)
  • Player Boost: Toggle player speed boost (on by default)

Requirements

  • ReturnOfModding
  • LuaENVY
  • ReturnsAPI

Installation

Place this mod folder in your plugins directory:

Risk of Rain Returns/ReturnOfModding/plugins/Doga-Tachyon/

Multiplayer

The mod uses the game's native artifact synchronization. All players will use the same Tachyon artifact when selected by the host. Difficulty scaling and player scaling settings are not synced, nor is custom rate - fiddle at your own risk.

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.

Dependencies

Install these first, or the mod will not work:
