Support upgrades

Support upgrades are gameplay enhancements featured in Halo 4.

Overview
Support upgrades are armor mods for the MJOLNIR [GEN2] armor that enhance a Spartan's combat performance in the field. They can be accessed through each loadout before a match is started or during a player's respawn time.

Ammo
The Ammo upgrade overrides the normal ammunition carrying capacity of the GEN2 armor, allowing a Spartan to exceed normal ammunition-carrying parameters.

Awareness
The Awareness upgrade adjusts MJOLNIR's heads-up display mechanics, allowing the integration of a motion sensor into scoped weapon smart-links. Thus, it provides a Spartan with basic motion sensor data while sighting an enemy.

Dexterity
The Dexterity upgrade speeds up weapon reloads and weapon swapping.

Explosives
The Explosives upgrade alters grenade performance, increasing blast radius and decreasing grenade damage received by the user.

Gunner
The Gunner upgrade increases how long a mounted weapon can fire before overheating. It also increases the user's movement speed when a weapon is detached from its turret.

Ordnance Priority
The Ordnance Priority upgrade offers more frequent ordnance drops to a Spartan. It is available only in modes in which personal ordnance is allowed.

Sensor
The Sensor upgrade increases the range and sensitivity of the motion sensor. It is utilized by stealth operatives and infiltration specialists to provide heightened intelligence of all nearby enemies.
