Quake 4 Call of Duty Zombies Mod

This project takes the source code for Quake 4 and modifies it to create a Call of Duty Zombies mode in Quake.
Goals for this project are:

• Create a desktop shortcut that automatically launches the mod
• README.md that explains the mod and its features
• Modified Main Menu
  • The main menu has been modified to fit the Zombies theme.
  • Custom "Zombies" text is displayed and various red elements have been added.
  • See mainmenu.gui in guis.
• Modified Heads Up Display (HUD) reflecting a key feature of the mod
  • The HUD has been changed with hints of red to match the changes to the main menu.
  • The HUD also displays the player's point count and which wave (number) the player is on.
  • The HUD updates as soon as either of the waveCount or points variables change.
  • See hud.gui in guis.
• In-Game Help Screen explaining mod changes
  • The Objectives GUI (wristcomm.gui) modified to explain the mod.
  • The player can press Tab in game to see the help screen.
  • The help screen gives the player advice and explains the wave system.
  • See wristcomm.gui in guis.
• Wave Based System
  • Zombies spawn into the game in waves.
  • Player is locked into the starting location.
  • Other AI have been removed (Morris, Anderson, Metcalf).
