The Sinking City 2 weapons split into four base-game categories - handgun, shotgun, SMG, and revolver - that any edition grants you access to. The Premium Edition adds the Chthonic Arsenal named weapons (Shale Mary handgun, The Breakwater shotgun, and Tektite Tommy SMG) and the Holloway Manor side mission's Bucking Bronco revolver, Kane's Hefty Barrel, Kane's Wrapped Grip, and revolver ammo recipe. No named base-game weapon is locked behind the higher tiers; every named premium weapon is a flavored upgrade rather than a required pick.
