Mass Effect Legendary Edition was initially announced in November 2020, but it only received a vague 2021 release window back then. Now it looks like the game might be coming out sooner than expected if leaks are to be believed.
However, this release date has yet to be confirmed or verified by either EA or BioWare, so take this with a grain of salt for now.
Mass Effect Legendary Edition will include the entire Mass Effect trilogy with updated “textures, shaders, models, effects and technical features” as well as all single-player DLC and promotional packs, remastered for 4K Ultra HD. We still haven’t seen any gameplay footage of the remastered game as of yet.
