About this project

Gungeon Online 0.101.0, MIT, drops into BepInEx. Steam lobby invites plus LAN UDP 27460. The host shares the run seed and the world/level/save state; enemy death and HP are synced but enemy attack simulation is not, so combat can drift. Verified with two real game clients over LAN using the mod's built-in test harness: both connected, picked different characters and generated the same floor (fingerprint 2A7BE448); a ~4 minute run had no disconnect or version mismatch. Write-up in games/enter-the-gungeon.

About this project

GungeonTogether 3-Player 0.10.8, MIT, drops into BepInEx and needs the ModTheGungeon API 1.9.2. Steam lobbies plus Steam P2P, aimed at 3 or more players. Marked AI Generated on Thunderstore and early: the published DLL (assembly 0.10.8.0) is ahead of its public repo (still 0.9.0), so it was reviewed from the decompiled binary (no URLs, file writes, process launches or native imports found). Boot-tested here in an isolated copy: the plugin loads, Steam initialises and the P2P/lobby callbacks register, but a real 3-client play session was not run (needs three Steam accounts). Incompatible with Gungeon Online; remove GungeonOnline.dll. Write-up in games/enter-the-gungeon.
