Death MK III takes after Death MK II but also adds its own uniqueness to the mix.
Death MK III has similar attacks to Death MK II, but also has its own unique set. As before, when the doors open, five missiles are released. Sometimes, they detonate with bullet patterns either spread towards the players or in sunburst. On higher difficulties/loops, these missiles have a stream of bullets trailing them. Unlike its predecessors, the doors are now vulnerable regardless if the doors are closed. Once the doors are destroyed, the laser shoots out as before but also a volley of smaller lasers are shot.
In addition to these attacks, there is a completely different phase that occurs soon after the fight starts. Death MK III will come to the front and attack from behind with bending homing lasers and bullets. Also, players should be careful of its entrance. It comes from the left to the right and if the players are not paying attention, they could ram into it.
- This upgrade can fire guns on its hatch after the hatch is destroyed, and this one can't fire Flying Cores as the same as the Death MK-I does.
- The homing lasers Death MK III can fire are more curved than from the succeeding bosses, which is more linear. This is a reference to the same attack from RayForce and Mystic Square.
