Witch Weapon is an action RPG with a story-driven single-player campaign, various multiplayer and co-op modes, a gacha system, and an anime-inspired art style. The game is inspired by the Japanese concept of haikuu, or the last hero, and is set in a world on the brink of disaster. You are the last hope for the world, and the only one who can save it.

The controls in Witch Weapon are similar to those of an action RPG. The player can move around the battlefield using the joystick and can attack enemies by simply tapping on them. However, the game has a different control scheme for enemies and bosses. When you attack an enemy, you will need to equip your weapon first. Once you have done that, you can use the power bar to unleash an epic attack.
