After installing the Ver. 1.2 update or later, clear Area 9 and achieve the true ending to unlock Destroyer Mode, accessible from the Extra menu at the title screen. In Destroyer Mode, Life Ups do not increase your maximum health and Energy Guard cannot be enabled. Enemies take more hits to destroy and their shots can go through walls. In top-down view, all enemies and bosses can only be damaged by specific Main/Sub Weapons, and in side view, when an enemy is destroyed, it fires a bullet straight towards you. All large refills for health, Gun Level and Jason's Sub Weapon ammo are replaced by small ones, and some upgrades for Jason and Sophia III are found in a different order.
