Dynamic, configurable spawning of vanilla Lethal Company monsters inside the Company building on 71-Gordion, on the navmesh baked by NavMeshInCompanyRedux. Host-authoritative: only the host spawns, clients receive enemies through the game's own netcode — so only the host strictly needs this mod (everyone needs NavMeshInCompanyRedux).
Built and tested against game v81.
[MinSpawnInterval, MaxSpawnInterval].Enabled, SpawnWeight, MinSpawnCount, MaxSpawnCount)
generated for every spawnable enemy type found in the game, modded ones included
(unknown types default to disabled).UpperFloorSpawnShare): configurable split between the
ship-landing level and the basement, instead of pure area weighting.OutsideEnemyShare): each spawn rolls which pool
to pick from, so dogs/giants/Old Birds actually show up when enabled.RespawnOnLoad: wipe and repopulate on every landing, or top up existing.DebugMode logging of every decision the spawner makes.Required (declared in the Thunderstore manifest):

Enabled, SpawnWeight, MinSpawnCount, MaxSpawnCount. Defaults: interior
threats enabled; outdoor giants/dogs/Old Birds, bees, Butler Bees and Manticoil

Requires the .NET SDK 8+ and NuGet access — game assemblies come from the
LethalCompany.GameLibs.Steam package (stripped + publicized), no manual DLL
copying.
dotnet build -c Release
Output: bin/Release/netstandard2.1/MonstersGordion.dll. Set the LC_PLUGINS
environment variable to your plugins folder to auto-copy after each build.

On every landing on Gordion (detected by polling StartOfRound.shipHasLanded,
host only) the mod triangulates the navmesh, welds it into connected regions,
anchors reachability in the main hall, generates patrol nodes, and starts the
spawn coroutine. Each cycle: roll interval → check GlobalCap → fill
MinSpawnCount deficits first, otherwise roll outdoor/indoor pool → weighted
pick → tiered reachable spawn point → RoundManager.SpawnEnemyGameObject →
two frames later force interior AI (SetEnemyOutside(false), custom node set,
agent warp) and roll the ToilHead turret. Leaving the moon stops everything and
(by default) despawns the mod's enemies.
