"Akimbo with improved hip spread. Can no longer aim down sights."
— In-game description
Twinsanity is an Epicgun perk in Call of Duty: Infinite Warfare. It allows the HVR and Auger to have Akimbo, which allows for a tighter hip spread and devastating damage up close. It is only available to the HVR - Gemini and Auger - Fury variants. It is worth noting that the Auger - Fury has tigher hip spread the longer it is fired, similarly to the DCM-8 - Epitath's Focus Fire gun perk.
