Developer Flying Wild Hog really burst into the action scene with their shooter Hard Reset back in 2016. After the co-op friendly Shadow Warrior 2, they began working on a single player only sequel. Apparently though they've also been working on a new game set in the old West that's not quite as grounded as say...Red Dead Redemption. Enter the Evil West.
A dark menace consumes the American frontier. As one of the last agents in a top-secret vampire-hunting institute, you are the final line between humanity and a deep-rooted terror that now emerges from the shadows. Rise up to become a Wild West Superhero, eradicate the vampire threat and save the United States!
In visceral, explosive combat, unleash hell with your firearms, lightning-fueled gauntlet, and gadgets. Kill bloodthirsty monstrosities in style as a lone hunter or in co-op with a friend. Explore and fight through a narrative-driven campaign while upgrading your weapons and hunting tools. Unlock new perks to evolve your monster-slaying mastery, crafting your own playstyle to defeat the supernatural hordes.A dark menace consumes the American frontier.

So it sounds VERY much like Shadow Warrior set in the old west. It'll feature two player online co-op. It's currently slated to hit all current and next-gen consoles along with the PC sometime next year. Here's the teaser trailer.
