How to Beat Hollow Boot Camp

1. Keep Enemies Outside the Ring
2. Break Canisters for Health and Energy

Keep Enemies Outside the Ring

Although Hollow Boot Camp features a blue ring similar to Dimensional Musketeer, you do not need to stay inside the ring to progress it to 100%.

For this commission, the progress bar will continue filling to 100% as long as there are no enemies inside it.

Break Canisters for Health and Energy

Canisters that refill health and energy are scattered throughout the stage. We recommend breaking them to recover health and gain more energy to access your agents' EX Special Skills!
