-Plasma pistol stuns most armor abilties since it stunts vehicles and disables shields.
-Armor details like vines with thorn, flowers, tiger stripes, etc.
-Halo radio, lets you listen to music will fighting. Music could be halo music or some sort of stations with music today. Useable in some vehicles and helmet. I know this is kind of stupid.
-Character voice editor like in sims. Raising or lowering pitch of voice to how you want it. That way all you have to do is buy the catch-phases you want.
-more attachment to make every spartan look different.
-Allow players to play as any covenant character ( except prophet) in invasion. Each comes with his own unique abilities. EX. Brutes-brazarker mode Grunts-suicide
-timer in firefight for next wave
-better forging material and controls. Maybe like sizing ,scaling, color, and what piece is made of: stone, metal, wood
These are just ideas. If you don’t like them fine with me, but I do care if you don’t tell me why. Maybe I can fix them. Also place some other ideas.
