The HM99 Magnetic Special Application Pistol is a handheld hydrogen-powered Gauss pistol, manufactured by, for use with specialised tactical VISRs, and augmented strength.

Designed for users that can handle the unit's weight single-handedly, the weapon's main purpose is a supplementary weapon for special forces operatives in areas of known Covenant remnant presence. Magnetic coils launch supersonic slugs from a top-fed magazine, designed to obliterate personal shielding, and cause massive damage to soft and hard targets, alike.

The weapon has not yet officially entered production, or use by special forces operatives. However, field and controlled lab testing displays high efficiency in its intended role as an anti-shielding weapon for use in close-to-mid range combat environments.

Project: ICEBREAKER
Created as a counter, and answer, to the Covenant's plasma pistol—renowned for its infamous effects on shielding systems and electronics when overcharged. The residual EMP effect has been known to permanently disable some electronics even within MJOLNIR armour. Hannibal Weapons Systems approached UNSC logistics officials with an idea for a weapon, capable of eliminating Sangheili, Jiralhanae, and potential hostile human target's energy shielding, and still retain enough kinetic energy to inflict potentially-mortal blows.

Hannibal Weapon Systems Engineers were briefed on the project shortly after, and Project: ICEBREAKER was born.

Early on in developmental history, the HM99 encountered various logistical hardships. The space required for both power supply and magnetic coils made the weapon too unwieldy to be condensed into a sidearm. While the weapon did achieve a limited amount of success in disabling energy shielding, it didn't quite have the necessary force to penetrate it.

With funding precariously limited, and Hannibal Weapons shifting focus onto Directed Energy Weapons, Project: ICEBREAKER was shelved for the better part of a year, while the engineers worked on condensing the weapon into a more portable version.

In the late final quarter of 2555, Project: ICEBREAKER was revived, and the engineers decided to move on from the ARC-920 disposable fuel cell route, and instead placed a dedicated power cell within the grip, and a secondary one above that near the 'slide'. As the weapon operates via electromagnetic acceleration, the slider is nonfunctional, and is not a slide at all.

Due to the increased power supply, the projectiles—up until then being relatively small—were enlarged. Titanium coatings were used on dense, lead ball-bearings to deliver powerful blows that would pierce through any but the most resilient energy shielding. Unlike the slugs of the ARC-920, these shots were still small enough to be featured in multi-shot magazines, fed from the top of the weapon, and powered by the same fuel cells so the magazine itself would feed shots into the barrel when the weapon was fired. The surge of energy would trip the capacitors to push the next round forward, into the chamber.

Project: ICEBREAKER was a resounding success, and a demonstration was scheduled for the following quarter.

Warzone
This weapon is available for use by Spartans in simulated combat environments onboard the UNSC Infinity, and other installations featuring combat simulations. It is a Legendary-grade Requisition, requiring 8 energy levels to call in.
