Resident Evil: True Director’s Cut is a patch by Deli295 for Capcom’s original horror classic that is supposed to be the most complete version of the game available, adding a bunch of things from previous Japanese releases that for some reason we never got in western editions.
While the West received numerous versions of the game from 1996, including an alleged “Director’s Cut,” none have included everything That was either in the Japanese Director’s Cut of the game or in previous demo and beta versions. This includes a slightly more explicit intro, a scene with a bloody message written on a wall, and some soundtrack omissions, all of which can now be found in Resident Evil: True Director’s Cut.
Nothing enormously, but if you’ve always wanted to play a version of resident Evil that includes everything that was ever made for the game – more than what the original Japanese made it Director’s Cut
