fastlorisstudios/UE4_EOS_Plugin
A plugin and sample project, built for Unreal Engine 4, that implements the Epic Online Services SDK
A 2020-era Unreal Engine 4 plugin that wraps Epic's own EOS SDK into an Online Subsystem, covering login and session management. It was archived by the author in the README itself — explicitly pointing you elsewhere. This is a dead project.
- Implements the UE4 Online Subsystem interface correctly, so it follows the expected plugin architecture rather than rolling its own abstraction
- Includes a full sample project (EOSBasic) with working DefaultEngine.ini configuration, which at the time was genuinely hard to find documented
- Auto-initializes and shuts down the EOS SDK at module load/unload — the right pattern for UE plugins
- The repo is self-archived. The README literally says 'THIS PROJECT HAS BEEN ARCHIVED' and tells you to go elsewhere. There is no ambiguity here
- Locked to EOS SDK v1.9 and UE 4.25 — the SDK is now on v1.16+ and UE5 ships its own first-party EOS Online Subsystem plugin, making this completely obsolete
- Only login via the Dev Tool was tested — no production auth flows, no friends, no achievements, no leaderboards; half the EOS surface area was never started
- The EOS SDK binaries are not included, so setup requires manual steps that reference a 2020-era dev portal workflow that has since changed
