Our friend, DarknessValtier, over on Nexus Mods has another Resident Evil 3 mod. This time with a mod to replace Carlos with fan-favourite S.T.A.R.S. member, Chris Redfield.
Like most mods, this one also requires the FluffyQuack Mod Manager (Fluffy Manager 5000). Once you download the mod manager, go to Darkness’ profile to download the Resident Evil 3 Chris Redfield mod.

Once you download the mod, copy the RAR file to \modmanager\Games\RE3R\Mods. Now activate the mod and launch the game!
If you have trouble and can’t find a Mods folder in the Fluffy Manager directory, just create one and copy the downloaded mod inside.
