Appalachian Onslaught

Appalachian Onslaught is an infinite roguelite defender about stopping waves of Appalachian cryptids from breaching the Mountain Pass. You build and upgrade a stronghold, command troops and fight the horde; the onslaught continues until you or your base falls.

Defend the Mountain Pass

Build towers and unit spawners to strengthen your defenses and expand your army. You can place buildings anywhere, rotate them and demolish them to adjust your layout to new threats. Four tower types include archer posts and arcane spires that call down lightning. You can command six troop classes, from Spear Warriors to Mountain Golems, and build unit spawners to increase your army limit.

Waves are randomized and feature 11 kinds of cryptids, from mutant boars to the Wendigo. Enemies include specialized classes such as siege-breakers and assassins, requiring you to adapt your defenses and forces.

Grow your forces

Defeated waves provide spoils you can use to unlock troops. These unlocks persist between runs, so troops you have unlocked are ready to deploy once you gather the necessary resources in a later attempt. Troops, defenses and abilities have no level cap and can be upgraded indefinitely.

You can also unlock active and passive skills for your Chief, turning them into a powerful fighter against the monster hordes. In Impossible+ Mode, you can permanently multiply your resource gains and push further into the endgame.

Survive battlefield events

Dynamic in-game events can change the battlefield. During the Blood Moon, surviving the event earns doubled or tripled rewards.
