The ongoing Bloodborne PS1 Demake project by Lillith Walther just showcased new work-in-progress gameplay featuring the boss battle with Father Gascoigne. The demake, being faithful to the original, retains the game’s cutscene (albeit with downgraded visuals) and uses the same voice-over. The Gascoigne boss battle is not only faithful to the original game through its cutscene, but it also retains the same movement and combat in its gameplay; it even added a button prompt when Gascoigne is open for a Visceral Attack.
Lillith Walther has been working on this Bloodborne PS1 Demake for quite a time now, with constant updates on the current progress through Youtube and Twitter. It utilizes a PS1 style visual with a retro-style version of the original BGM completing the feel of a PS1 game. Weirdly enough, the Bloodborne Demake looks gorier compared to the original (at least for me).
There is no word yet on a release date or if they will release a demo but there is a word that they won’t be demaking the entire game. You can follow Lillith Walther’s progress through Youtube channel.
