The Mantis is replaced by the Promethean Combat Capsule. Like the Prophet's Gravity Throne, the Combat Capsule appears as a floating platform upon which the operator sits. Unlike the Gravity Throne, the Combat Capsule's operator is protected by a hemi-ellipsoidal bubble of hardlight surrounding the top side of the floating platform. The egg shaped hardlight bubble can be temporarily disabled, through damage or an EMP attack, leaving the operator exposed and vulnerable to direct fire. The Combat Capsule can only be boarded once the protective hardlight bubble is disabled but it can be boarded from any direction.
Similar to Covenant hover tech, the Combat Capsule can quickly accelerate in any horizontal direction but its top speed is fairly slow. Unlike Covenant hover tech, the Combat Capsule hovers much higher, at approximately 1.5 Spartan heights off the ground, allowing players and vehicles to pass underneath unhindered. Jump gives the capsule a momentary increase in altitude before coming back down to rest at the standard hover height. Crouch toggles between hovering at the standard hover height or at a low, close to the ground, hover height. Melee attack is disabled while crouching.
Tapping melee causes a miniature Incineration Cannon style projectile to be fired straight down from the underside of the floating platform. The splash damage radius is smaller than Halo 4′s Incineration Cannon but it still disintegrates infantry and destroys vehicles on contact.
The vehicle operator is capable of simultaneously firing both an automatic, non-headshot-capable Sentinel Beam, by holding the left trigger, and a semi-automatic, headshot-capable Particle Beam by tapping the right trigger. The "overheat threshold", the point at which the weapons overheat, is higher than on standard infantry weapons but both of the Combat Capsule's weapons, the Sentinel Beam and the Particle Beam, share one battery.
