The last bunker stands on a contaminated planet. Develop skills, merge them, and deploy units to defend against monsters attacking from every direction. ■ Random Skill Development Skills are generated randomly during battle. Use Pyro, Frost, and Electro skills to fend off the incoming monsters. ■ Merge to Grow Stronger Merge skills of the same tier to obtain higher-tier skills. Even low-tier skills can become powerful combat resources through merging. ■ Complete Combinations to Deploy Units Each unit requires a different skill combination. Complete the required combination to deploy powerful units that will join the battlefield and help defend the bunker. ■ Endless Waves The monsters never stop. Repeat skill generation, merging, and unit deployment to survive increasingly intense attacks. ■ Grow After Battle Use battle rewards to upgrade your units and skills.
