Jbmod is the mod that has inspired Garry's Mod. And it's also the very first Half-Life 2 mod.

Please note that i'm running the old version of Jbmod 0.5 that run on the old source engine. It's not the same Jbmod 0.5 there is on steam !

Jbmod 0.5 is suppose to be run on the very old Half-Life 2 engine. In this video i'm running the mod on a custom version i made base on the Source SDK 2006, for having the Half-Life 2 maps and scripts working again.
