Undead Slayer is a free action game for mobile developed by NHN Entertainment. It is a hack-and-slash RPG that is set in ancient China and employs a martial arts theme. In it, players take control of a wandering warrior who travels across the continent, battling hordes of the undead.

Similar to Samurai II: Vengeance or Shadow of Death, Undead Slayer is all about the action from start to finish. Players will collect weapons and gear along the way to help grow and make their character stronger as it they face bigger and more difficult enemies.

Is it any good?

Undead Slayer is a 3D action game that is set in ancient China. It is basically The Romance of the Three Kingdoms with a zombie twist to it. It is set during the warring period wherein the land has been overrun by the undead. You play as a wandering warrior that is tasked with traversing the land and cleansing it of the hordes of monsters that plagues it.

Undead Slayer features more than 90 levels spanning its entire map. Each stage has waves of enemies that you will need to face and survive to progress. Controls have been optimized for touch input and are easy to learn. Tap anywhere and your character will automatically attack any enemy it encounters along the way. You can double-tap to dodge and activate skills by selecting their corresponding on-screen buttons.

Various items, as well as HP and Skill orbs will drop randomly during battles, and this is one area where the game could use improvement. Since your character acts autonomously, it will often prioritize fighting enemies over collecting items at any given moment. This is rather unintuitive and clunky considering there's only a small duration before drops disappear, with you often missing out on rare drops.

Fast-paced, challenging, and a lot of fun

Overall, if you're looking for an action game that is simple yet a lot of fun to play, give Undead Slayer a try. It's fast-paced and challenging, features simple and intuitive controls, and has plenty of levels and items to loot throughout your adventure to make your character even stronger. Highly recommended.
