I completely agree with Armor-Plated Hank. I would like it if 343i created a second built-in game type for infection which allows the following:
customizable armor color
customizable load outs for flood/zombies
Halo 3 VOIP customization
removable red overhead name
sprint toggle
weapon placement in map
flood vehicle splatter damage/vehicle weapon damage
If 343i did this I would be able to create new custom games, or bring back old games such as Hot Pusuit and Splatter Monkey.
