QuakeStyle ZX's Weapon Wheel is exactly what it sounds like. You can pause or slow down time (or neither if you so desire)
and select weapons and inventory items from a nice big wheel of stuff.

The wheel is an adaptation of gleasspty's Weapon Wheel mod, originally made for Project Brutality, but later made available for many many other mods. This mod uses the template provided with the main mod download and would not be possible without his amazing work 
(and the work of the fine folks listed below) and all the help he provided when things were going horribly wrong. -Vermi and Xterra

Original idea due to Loismustdie555.
Graphics due to DoomNukem
saegiru for UDV HUD
id Software for Doom
Other original code due to Stan423321, Zhs2, PillowBlaster, The Zombie Killer and Nash
Ammo font due to Kinsie / id software
