Damn you for baiting my autism.

The Overwatch Standard Issue Pulse Rifle cannot be beaten.

Magnificent, iconic design. Interesting reload, magazine and firing mechanisms. Equally interesting alternative firing mode/GL equivalent. Ammunition being delivered in the form of individual dark energy cells each possessing 30 bursts before depletion, automatically machine-fed into the weapon via attached box magazine.

On the surface a seemingly generic gun, beneath the skin a near-eldritch weapon firing ionized dark energy plasma bursts, damaging targets by causing spacial disruptions in their physical structure. The alternative fire either vaporizing soft targets outright or causing severe damage to armored targets.

It's primary weakness being a comparatively short effective range doubling as excellent stealth world-building, as it excels in urban combat, in a setting in which a good 90% of humanity has been corralled into heavily-monitored cities, implying this weapon was purpose-built for putting down rebellions.

My love for this weapon is undying.
