About This Game

You can't defend without a base!

Choose between a vast range of defences to strengthen your base, whether that's through increasing your army limit via building spawners, or by stopping the enemy with sheer firepower, by choosing from an array of defensive towers, ranging from simple archer towers, all the way up to towers that can call forth lightening from the sky to strike down your foes!

And before you ask, buildings like spawners can be placed anywhere you like, and there is a lot of flexibility to the building system, such as rotating and demolishing buildings to suit your Chief's needs.

Trying to face the onslaught alone? Don't bother.

Use your rewards from defeating waves to unlock brand new troops to forge a tribal army that rivals even the most brutal of cryptids! As a roguelite, all unlocks remain permanent, so that even if you die, and everything else resets, you'll still have all your troops, ready to go, as soon as you have the resources to build them.

To make sure the enemy doesn't overpower your troops, make sure to upgrade them, with the lack of an skill cap meaning you can create some truly god-like units!

Your goal is simple: stop the Appalachian cryptids from breaching the Mountain Pass. In this roguelike defender, the waves only end when your base falls. Keep building, upgrading, and fighting to prevent the wilderness from reclaiming the land.

  • Multiple enemy classes to fight against (such as siege, general, assassins etc)

  • Randomised waves to keep each one varied and dynamic, no two waves are ever the same

  • Roguelike progression - Infinite levels to upgrade to make some incredibly overpowered troops, defences or abilities

  • Post-Launch support - After the game launches, more content such as new troops and enemies will be added based on player feedback

  • Unlock (currently) 5 different troop classes, ranging from weaker units such as the spear warrior, all the way up until you unlock mountain golems!

  • Choose between 4 different towers, each with completely unique abilities and use-cases

  • Upgrade you Chief's skills, with active and passive abilities to make your Chief a nightmare for the cryptid hordes

  • Fight off (currently) 9 different enemy types, ranging from mutant boars to the wendigo itself!

  • Reach Impossible+ mode to increase your permanent resource multiplier, allowing you to go further and further into the game as you progress!

  • Dynamic building system, with free-placement aligned with tools such as rotating and demolishing buildings

  • Event System - Random events like 'Blood Moons' will occur throughout the game, and if you survive, your rewards double/ triple
