Enemies could get sidearms (pistols) to increase weapon viability

[theastropath]

Pistols aren't very common in the late game, which makes them a worse choice over the course of the game.

Enemies could possibly have a chance to receive (or always?) a sidearm like a pistol/stealth pistol/crossbow alongside a more significant weapon type (like an assault rifle or assault shotgun). This could make pistols more viable as a long term choice through the game.

we could probably also give them regular darts or flare darts, I'm guessing if you just don't give them tranq ammo and manually set the ammo/projectile properties in the weapons, it should just work

looting the ammo works based on weapon.AmmoName
