Stage 7 No Escape Run Playthrough (Rhythmic Echoes in the Pavilion)

Strenghten the Frontline

This stage has multiple waves of running enemies that will rush past your defenses. Make sure you have defenses set up in the front to deal early damage.

Construct Mechanici near the escape point

After building up your defenses upfront, the next step is to build towers at the rear. Having a Cryo and Hydro Tower, along with an Ambush Mine can help prevent escapees.
