Zombie Slayer Full Release file

Many of the better changes have been done from people who have helped out with the mod. I would like to thank the following people:

• 6th Venom for helping with the button interface at the last second and Neurological for helping convince me that the interface was seriously hosed
• Mystic Realmz for creating the soundtrack
• Gazz (former lead designer of Classic Doom for Doom 3) for doing level design work in his spare time
• David Kosta for creating the excellent 2D art work you see in the loading screens
• deadite4 for supporting the mod with miscellaneous tasks
• all the voice actors for understanding the script and getting a feel for the characters by themselves instead of taking the script literally
• the mod/gaming community for their valuable input on the demo
