Introduction

Resident Evil 6 (2012) originally supported local split-screen on consoles, but the PC version famously omitted LAN (local area network) play. Over the years, community fixes emerged to restore LAN functionality, allowing players to connect multiple PCs locally without relying on Capcom’s now-inconsistent Steam matchmaking.

This feature covers the most recent (2023–2025) updated LAN fixes — specifically the improved RE6_LAN_Fix and modified Steam API wrappers that work with the latest Steam client, Windows 10/11, and the final game version.
