With obvious influences through coldFUSI0N’s thread, I know how some people are against Reach’s AA’s. What if AA’s were replaced with special grenades. Use the D-pad to switch through them and free up a button. Your, i guess we can still call it this, loadout is just a special grenade you get with your frags and/or plasmas when you spawn. Example:
Camo: anyone hit with this is temporarily invisible for 30-45 seconds
Cryo: freeze and enemy but doesn’t kill unless the enemy has no shields, also can close up a doorway or create an ice-bridge for tactical use
Incendiary: napalm set ablaze with a splash effect, touch it and you die!
EMP: knock out shields but has a low range (EMP is a very strong, one headshot or melee and your dead)
Shield: like the drop shield with a bubble for protection and slow health regeneration
Anti-gravity: can create an easy way to get around or fling an enemy or enemy vehicle fly off the map
They can only be used once, but can be recovered from dead enemies; however, it will still be the grenade you selected. This is just a thought and my versions of these may not be perfect, but post what you think!
