FIFO Shared Upgrades for R.E.P.O.

A BepInEx/Harmony mod for R.E.P.O. that shares every player upgrade with the whole team.

How it works

• A thread-safe FIFO queue collects every upgrade taken by any player.
• The queue is drained on the Unity main thread every frame, guaranteeing ordered, race-free application.
• Each upgrade is broadcast to all connected players using a Photon RaiseEvent, so the whole crew receives the same benefit.
• Late-joining players are caught up by syncing the current highest level of each upgrade.

Features

• Any player can grab an upgrade — it immediately applies to everyone.
• Host-only mode by default (only the host needs the mod).
• Supports vanilla and modded upgrades as long as they appear in StatsManager.
• Configurable late-join sync and frame-processing limit.

Notes

• The mod uses reflection to stay compatible across game and modded-upgrade updates.
• If you disable HostOnlyMode, all clients must run the mod for sync to work correctly.
