Endless Night

This mod allows you to do an endless run. If it is enabled, you should be able to see new challenges in your pitch-black stone. Endless runs can be Underworld only, Surface only or mixed (starting with the Underworld route). After each successful route clear you will be transported into the beginning of the (other) route. Afterwards, all enemies get healthier and biomes get shorter. Also, one more Olympian God can appear. This continues until every Olympian can appear, which marks the beginning of your last route. Thus, there will be 6 routes in total.

Installation

Install this mod using r2modman from Thunderstore. Details can be found here.

Configuration

NOTE: When using Hell2Modding, the configuration file is located in the ReturnOfModding/config folder of your r2modman data folder under the name Siuhnexus-EndlessNight.cfg.

The mod comes with a config file that allows you to change certain settings. The following settings are available:

• enabled: Set to true to enable the mod, set to false to disable the mod. Default: true.
• loglevel: Prints out all message types up to this value. The different types are 1 (Error), 2 (Warning), 3 (Success), 4 (Info). Default: 2 (prints errors and warnings).

Known issues

• Sometimes the background music of the wrong biome is playing, or the music stops altogether
• After entering a Chaos door in Ephyra, you can be offered a door to a room otherwise only reachable through the Ephyra hub room (does not cause crashes)

Roadmap

• Balance certain boons (e. g. Chant offered by Chaos) for endless runs
• Increase amount of hex upgrades to benefit more from Paths of Stars in endless runs
• Add different configurations/difficulties (increasing fear, enemy scaling etc.)
