2 years in development, TEA is a stealth-action mod that attempts to replicate Metal Gear Solid’s gameplay in the GoldSource engine.
The entire 3rd Person Technique was developed with countless Entities with no extra code.
Apparently, it’s already out, which is pretty great, but apparently there are quite a few bugs.
Perhaps the modders should have taken a bit more time to polish up the mod.
Still, it’s well worth a try!
