Dark Fog Awakening

A BepInEx mod for Dyson Sphere Program that lets you awaken the Dark Fog enemy faction in a save that was started with combat disabled.

Features

• In-game button appears only during active gameplay sessions (not the main menu).
• Two-step confirmation so you can't trigger it by accident.
• Colonised planets are protected — ground enemy systems are never seeded on planets you have already built on.
• Hives spawn at the farthest stars from the galactic centre so the threat starts distant and spreads inward.
• Configurable hive count and aggressiveness multiplier.

Installation

Thunderstore Mod Manager (recommended)

Search for Dark Fog Awakening in the Dyson Sphere Program community and click Install. BepInEx is installed automatically as a dependency.

Manual

1. Install BepInEx 5.x for DSP.
2. Drop DarkFogAwakening.dll into BepInEx/plugins/DarkFogAwakening/.
3. Launch the game.

How to use

Load a save that was started with the Dark Fog disabled (peace mode). A small window labelled "Dark Fog Awakening" will appear in the centre of the screen. Click Awaken the Dark Fog → Yes — Awaken Now.

There is no undo. The fog does not go back to sleep.

What happens on awakening

1. GameDesc.isPeaceMode is set to false and CombatSettings difficulty values are initialised (multiplied by the configured aggressiveness factor).
2. The N farthest non-colonised stars each receive a hive via SpaceSector.TryCreateNewHive, then SetForNewGame() and Realize() are called to fully activate it.
3. Ground enemy systems (EnemyDFGroundSystem.LoadPattern()) are initialised on all planets the player has not built on.
4. The save is unmodified until you manually save — the changes are applied in-memory and will persist from that point on.
