📋 About This Mod
Beneath the surface of the earth, horrific experiments using the forced evolutionary virus were carried out on unwilling participants in Vault 87. It's results are now more apparent then ever, as biomass creeps intothe vaults corridors. Takes inspiration from Fallout 1, where we can see the masters biomass taking over its surroundings. Implications that the FEV being used is spreading throughout the vault itself, as a living, breathing home to the DC super mutants.
