Yeah no offense. Not sure why anyone would use the old version by an author who will likely never code for L4D2 again or be seen on this forum again. Versus an author that has pretty much perfected the plugin, while fixing old outstanding bugs.
It would be like using the original bebop when you have Merudo's Superversus that fixes pretty much every bug known in the original superversus and the original bebop.
The only thing left to fix now that ragdolls have been fixed thanks to Mr. Zero and the older plugins like multiple equipment/superversus/FakeZoey/Model Vocalizations from Merudo/Mastermind/Cravenge.
Is this...

Deathchaos made progress apparently. Then life/boredom/problems got in the way.
