The new Resident Evil 3 looks to be a generous package by any definition, as it includes both a full remake of the original game along with the new multiplayer experience Resident Evil: Resistance, which appears to be almost a full game in its own right. That said, it does seem a few features from the 1999 game won’t be making the cut.

The original Resident Evil 3: Nemesis occasionally forced players to make quick decisions, which would lead you down different paths, eventually culminating in several unique endings. Well, it seems like the new RE3 is dropping that in favor of a set story. In the latest issue of Official PlayStation Magazine UK Capcom producer Peter Fabiano was asked whether Resident Evil 3 will have multiple endings, and he gave a straightforward “no.” So, there you go! Fabiano didn’t expressly mention whether the branching paths will be present, but presumably they won’t be if there’s only one ending.
