As you might have guessed from the name, BioRand is a randomizer mod for the classic, original Resident Evil trilogy, pre-remakes, and a long-running passion project continually updated by a large team of RE community oddballs. Normally a randomizer just reshuffles where key items and enemies are placed, forcing you to forge a new path through the game. And while you can do that with BioRand, it also lets you do so, so much worse more.
If I want to cross-wire every door in the game to lead somewhere different? Easy. Completely reshuffling the characters and their voice lines to create unhinged adlibbed cutscenes? One click. Fill every single room in the game with enemies, including 'safe' areas? Sure, why not.
And on top of that, it comes with a huge library of alternative characters from across the series, fully voiced. Alternative enemies (I just fought a mutated Steve Burnside as Regina from Dino Crisis), and even randomized soundtracks to really put a fresh spin on these familiar survival horror classics. Does it make sense that Salazar (the tiny evil Napoleon guy from Resident Evil 4) is leading the STARS team? Absolutely not. But playing as him is an absolute blast. Especially when the game starts me off with a magnum revolver and enough ammo to kill god. Guess he's just getting even.
