About This Game

Grimstone Valley is a third-person supernatural action game set in the wild west. Utilize an eldritch arm comprised of powerful tendrils to reposition enemies and control your environment, taking advantage of deadly and alien objects to defeat your foes in fast-paced, tactical combat.

Save your home.

A doomsday cult attempted to sacrifice you to an unknowable power. They failed. You survived, but the ordeal cost you your arm. In its place now grows a powerful mass of tendrils that move as though they’re alive.

Now, the cult’s machinations have twisted the whole of the valley into a nightmarish hellscape overrun with monsters. With your newfound power and a tenuous connection to the force on which the cult calls, you may be the only person capable of stopping them.

Master your tendrils.

Your alien arm gives you complete control over the world around you. With keen eyes and quick thinking, you can use your surroundings to deal devastating blows to the valley’s alien invaders. Smash them, impale them, burn them, even blow them to kingdom come.

Enemies are vulnerable as well; control their movement and launch them across the battlefield to keep yourself out of harm’s way. Eldritch growths and mundane defenses alike can be turned against your foes with smart positioning and practiced aim.

Work with the people of the valley.

Grimstone Valley may be nearing destruction, but its people are still holding on. Survivors hide out at The Last Spike, a saloon on the outskirts of town that’s been turned into a hub for the local rail workers’ union.

The Spike is home to a host of survivors that you can speak to, learn from, and lean on for support. You may be the valley’s last line of defense, but this fight isn’t yours alone.
