Phase 1: Arm Attacks & Wind
This boss has powerful arm attacks and wind-based abilities. It will swipe its arms across the arena; jump or slide to avoid. It also creates powerful gusts of wind that push you. Use your Flash Shift to resist the wind and get close to its head. Focus fire on its head with charged shots and missiles. When it slams its arms down, it creates shockwaves. Jump over these. Be prepared for a melee counter opportunity when it charges at you.
Phase 2: Wall Climbs & Air Blasts
In the second phase, Experiment No. Z-57 will climb onto the walls and ceiling, firing powerful air blasts. These blasts can be dodged by moving to safe spots or using Flash Shift. When it's on the ceiling, it will often create a vacuum that pulls you towards it, followed by a powerful blast. Use Flash Shift to escape the pull. Continue to target its head. When it returns to the ground, it will often create a series of wind tunnels. Navigate these carefully and keep up the pressure. Another melee counter opportunity will arise.
