Jump onto the crumble blocks to make them solid, then use them as a platform to cross the room. With Grapple, a running jump then single Grapple swing can be used before PLMs are overloaded, alternatively jump on the crumble blocks and Grapple the Ripper. In indirect G-mode, stand where the gate will spawn and exit G-mode to open the gate. In direct G-mode, overload PLMs by shooting the gate then position Samus a few pixels away from the gate to where upward diagonal shots go through it. Crouch then shoot diagonally and quickly exit G-mode (3-7 frames later) to open the gate on G-mode exit.

Dev note: The canComplexGMode is only used here to describe opening the gate in direct G-mode without gate glitching. However, the indirect variant still requires canHeatedGMode or Varia - with Varia, indirect strats can instead be used to go to the top left door and return.
