The world suddenly plunged into a zombie apocalypse. When all humanity was in a desperate situation, some heroes with supernatural psychic abilities emerged, and these superpowered individuals became the hope of mankind. Facing the constantly evolving zombie threat, a superpowered individual named "Alice" stood up. She could control all metal weapons through her psychic powers and led a team to search for hope of survival in the zombie tide. In "Superheroes", you will embark on an adventure full of surprises and challenges. When entering battles, you will face various combat tasks. Through a simple and convenient operation method, click the screen or buttons to select the skills you want to upgrade. Different skills have different effects and powers. Some can cause huge damage, some can provide defense bonuses, and some can even control enemies. During the battle, you need to flexibly select the appropriate moves based on the characteristics and attack situations of the zombie tide on the opposite side, grasp the battle rhythm, so as to achieve the goal of defeating the enemy. As the game progresses, you can obtain experience and precious resources by completing tasks and defeating powerful enemies. Using these resources, you can upgrade your skills, enhance the attributes of your character, and unlock more powerful weapons and skills.
