Note: This HUD is a modification of Yatar's HUD.  So give him credit too!

Installation

1. In Explorer, go to:

WinXP: %appdata%\id Software\quakelive\baseq3\

2. Create a folder called "ui" (or switch to that folder)

3. Put the "oringe" folder and oringe.cfg in "ui" folder

4. Add the line
       seta cg_hudfiles "ui/oringe.cfg" 
to your config (qzconfig.cfg or autoexec.cfg)

the Hud will overlap the gun model

Timing is the most important aspect of Quake, and I was always forgetting to look at the tiny timer in the corner of the screen when I picked up items, so that's why I moved the timer to just above center and made it really big!  

NOTE: Due to a currently undiagnosed bug with the HUD engine numbers,
HUD will sometimes not be displayed when the HUD is first loaded.
Simply execute "loadhud" in console and the HUD will be complete.
