UW's weapon roster has been expanding.
Not just in the total number of guns, but also the period in which they've been drawn from.
Obsolete 19th century black powder long guns brought back into service and the latest in 1940s firearms development for field testing, plus everything in between.
Each UW's weapons classes (e.g. single action rifle, shotgun, etc.) each feature a diversity of calibers and functionality.
As a functionality example, the shotgun class features both buckshot and slug firing shotguns.
As a diversity example, the single action rifle class includes straight-pull military rifles, breach loading safari guns and pistol caliber lever action rifles.
The sidearm weapon class is the most diverse, featuring handguns, carbines, machine pistols and sawn down rifles and shotguns.
Whatever the drawbacks of your character's primary weapon, there will be a sidearm to complement it.
In most cases, switching to your sidearm is faster than reloading too.
What is the relevance of weapon classes though?
Each of UW's characters has preferences for certain weapons classes in the form of bonuses and penalties.
Valeria as an example (gripping the Type 11 in the screenshot), has a reduced jam and degradation rate for automatic rifles, but deals reduced damage with shotguns.
But as previously stated, there are a wide gamut of types of weapon per class, so no character will need to be pigeonholed into playing a certain way.
Mix and matching guns to each character's preferences is another path for you to exercise your combat creativity.
