About this project

BepInEx 5 / HarmonyX plugin for the original Gedonia (Steam app 1114220, build 16727998; not Gedonia 2), built from zero. Steam P2P through the game's own Steamworks.NET (friends-only lobby of 4, in-game invites) or plain UDP in the home network (LAN discovery). Host-authoritative: enemies, followers and world events have one tester with epochs; story calls (dialogue answers, triggers) run on every machine in the host's order; shared conversations with voting; groups (combat XP and map markers per group); enemy scaling by group size near the enemy (host's settings); trading as a two-phase commit with the host as coordinator; spell effects and transformations shown to others; cutscenes start when every player confirms; chests, gathering spots, expeditions with seeded generated dungeons, travellers, time and weather, sounds; respawn crystals replace the reload-only death screen. QA: two game clients on one PC driven by test steps and bots (scripts/test-local.ps1, 38 scenarios, logged assertions and screenshots); real sessions of the tester with friends over Steam went fine, their findings fixed in 0.7. Each player keeps their own save. Write-up in games/gedonia/. MIT licence.
