The M98 Compact is a UNSC small calibre bullpup pistol. It has an uzi-style grip in the centre of the pistol but then a roughly visible L shaped magazine, though in its entirety is more C shaped (with translucent plastic and titanium alloy versions available) containing triple-stacked rounds. The weapon has automatic, burst and semi automatic firing modes as per standard, making it more of a pistol carbine. It fits a over and under pistol rail. The weapon comes in a electroless nickel, black polymer or titanium alloy finish.


The M98 has seen extensive use with soldiers that can neither afford the M6's weight or low magazine capacity, especially those fighting lightly armoured enemies or fighting in extended warzones. It is also highly favoured by special forces for its high amounts of fire.


The M98 is a blowback operated, selective-fired weapon which fires from closed bolt. The firing is controlled by a trigger unit with a conventional hammer. A manual safety is located directly above the trigger. The magazine fits part of the section into the pistol grip then the other end into the ammunition feed at the end of the pistol, behind the pistol grip, feeding from front-to-back, with spiral ramp built into the "rear" part of the magazine. Spent cartridges are ejected out of the firing chamber just above and slightly rearwards of the grip. The slide to cock it is like that of any conventional pistol. The fire selector is located directly above the grip. It has fully adjustable and removable day/night iron sights.

UNSC Comments

"You plant both hands of the thing and it'll turn into a micro SMG."

"Reminds me of the M12 but a lot smaller and less prone to giving you a black eye."

"During the three day siege of Berinsgrad, I started using this thing on burst fire against troop formations coming through the square while my buddy tried to reload my AIE."
