What it is

BioRand is a free Windows randomizer for PC releases of Resident Evil. It can change weapons, ammunition, items, enemies, music, characters, enemy positions, keys, doors, starting inventory, cutscenes, difficulty, and item ratios. Door randomization rebuilds room connections into an alternate route, while key items are placed so they can be reached before the doors or objects requiring them. Options include item ratios, enemy difficulty, segment size, supported characters, and voice changes. A custom item pool can replace every pickup with a random item type and quantity; otherwise, base-game items are shuffled. Music is shuffled by genre, with custom WAV or OGG tracks supported in designated folders. Seeds can be shared as QR codes or alphanumeric codes, and a text spoiler log lists key locations and weapons. Listed games include Resident Evil, Resident Evil 2, Resident Evil 3: Nemesis, Resident Evil 2 (2019), Resident Evil 4 (2023), and Resident Evil Requiem (2026).
