Viz - Quake 3 mod
Hentai, the man behind the original Quake 2 VWep mod is back with "Viz", a mod for Quake 3 that adds a ton of server and client configurable options.
These include bleeding, a "big head" mode, an alternative rail effect, decapitation, hit location based damage, and the ability to make the models behave differently, each with their own individual speed, jump height, mass, health, hitloc target sizes etc. Funky.
