Our Metro 2033 Redux +9 trainer is now available for version 04.06.2020 and supports STEAM EPIC STORE, WINDOWS STORE, XBOX GAMEPASS FOR WINDOWS.
There is no GoG version support. That trainer is for STEAM.
To submit a request for a new distribution platform, please use our trainer requests system. Once at least 5 people request the same distribution, it will be available for funding. Please do NOT use the trainer option request system to request new platforms as they will be denied. Premium members at any level may request a new distribution as long as it’s done through the normal request system.
