According to the synopsis, this game is a “Wild West-themed roguelite FPS” where you play as a “gunslinger in limbo, involved in a gritty war against “The Cartel”, a ruthless organization harvesting souls to break free of the shackles of the afterlife.” So that sounds like a Weird West to me!
Just from watching the video, I wasn’t sure if it’d be a Weird West or not. Some of the architecture looks Western but other parts just look like ancient ruins. It’s weird how the architecture is the deciding factor here, since there’s also the game Witchfire which looks to have the same game mechanic of casting spells with a gun. But Witchfire definitely uses more European/Medieval architecture in their level design. So Witchfire doesn’t appear to be a Weird Western to me. Yet given the synopsis for Soulslinger, I’ll say that one is a Weird Western. It’s weird where I draw the line.
Anyway, Soulslinger is in Early Access on Steam and Witchfire is in Early Access on the Epic Games Store.
