Not to be confused with Lord British's laser weapon, the Disruptor.

Disrupt (ディスラプト Disuraputo?) is a boss in Gradius III.


Disrupt is a gunwall which first appeared in the arcade version of Gradius III as the first sub-boss of Stage 11. It reprised this role in the Super NES port of the game as the first sub-boss of Stage 9. In both appearances there are three cores with four barriers each, several laser cannons and four hatches, two of which spawn Duckers while the other two spawn flying enemies.

Attack patterns

Disrupt's attack pattern is simple, it fires from the laser cannons while periodically releasing enemies from its hatches. In the arcade version, there are moving floor and ceiling wall sections that severely limit the player's movements, and the hatches cannot be destroyed. The SNES incarnation doesn't have moving walls and the hatches can be destroyed in order to leave the gun wall defenseless. On higher loops, each of the barriers will fire suicide bullets when destroyed, although they're fairly easy to dodge.

Version differences

In the arcade version of Gradius III, this boss is no pushover due to the moving walls that may crush the player's ship if not careful. It's likely that some Duckers and lasers will try to shoot away in order to distract the player from evading these wall sections. In the SNES version of the game, however, the gun wall displays a much different behavior; namely, the moving walls are removed and that alone makes the boss much easier to manage. In addition, the hatches can now be destroyed and the player's ship can actually go inside of the core at some point with careful maneuvering. Compared to the arcade version of the boss, the SNES incarnation is much easier.
