JBMod is a modification of Half-Life 2 that activates the physgun and adds many new features.
JBMod was originally made because the nerds on HL2World wanted to get back to making sexual poses with the ragdolls in Half-Life 2, which they weren't able to do anymore since the physgun had been removed from the final game. Both prior to the release of Half-Life 2, and after the release of JBMod, just about every screenshot involved Alyx Vance.
