BioRand
What it is
BioRand is a free Windows randomizer for Resident Evil games released on PC. It can change weapons, items, ammunition, enemies, music, characters, enemy positions, keys, doors, starting inventory, cutscenes, difficulty, and item ratios. Door randomization rearranges room connections, while key items are placed so they can be reached before the door or object that uses them. Settings include item ratios, enemy difficulty, and segment size. Players can shuffle existing items or use a custom pool that replaces each pickup with a random item type and quantity. Character and voice options can alter NPCs and their lines; music is shuffled by genre, with custom WAV or OGG tracks supported. A generated seed can be shared as a QR code or alphanumeric code, alongside a text spoiler log of key item and weapon locations. BioRand lists support for Resident Evil, Resident Evil 2, Resident Evil 3: Nemesis, Resident Evil 2 (2019), Resident Evil 4 (2023), and Resident Evil Requiem (2026).
