Surrounded by barren and desolate deserts, you will lead your squad against countless undead skeletons. Each battle is a fierce survival challenge with fast-paced and intense pressure. Collect and fuse heroes to create more powerful warriors. High-level characters are equipped with powerful weapons and equipment, making them the backbone of your squad. After each upgrade, you will be able to choose 1 of 3 random buffs — increasing damage, reducing cooldown, or supporting defense — to adapt your tactics to each attack. How long will you last in this dusty hell?
