Have voice commands using a microphone or xbox kinect been considered for in game weapon switching. But instead of saying xbox... you would say ghost.. switch to/use --insert name of item/ ammo use--. Just for less menu time mid fight. On screen cooldown should be considered also for synths But still left as an optional choice. And i guess most names of weapons cant be prenounced so clear into a microphone but saying switch current primary/sec/heavy and then choosing 1-9 of on screen "hologrammed thumbnails" could work
