Be careful to avoid the stationary, invisible projectiles that the pirates spawn from where they jump. It is possible to exit G-mode and quicky pause abuse, to collect the pirates' drops and get to the door.

Dev note: It is possible to enter the room in direct G-mode, kill the pirates, return to the open door, then exit G-mode and quickly touch the transition to awaken Zebes (but not get the metal pirates kill flag). This is not included, as it is a very niche knowledge check, and at that point, you might as well pause abuse to get the pirate drops and both flags.
