@Gamebanshee they report that the mod for Hellgate London, London 2038 is ready for pre-alpha testing and are now accepting volunteers. You will need an original Hellgate London retail installation with the single player v1.2 patch and multiplayer 2.0 patch.
More information.Please use this form to express your interest in pre-Alpha testing London 2038. The pre-Alpha state of the game is not anywhere near bug-free, and should not be expected to be played as if it is a stable, retail product. We need testers, not people just playing for fun. We need your help in identifying issues and inconsistencies, and appreciate your interest! You MUST join Discord and express interest before being considered, thank you!
