Steel Diver is a unlockable stage in Super Smash Flash 2 hailing from the from the Nintendo 3DS game of the same name.

Despite being confirmed in SSF2 Dev Blog #8, it was leaked several months beforehand when a couple of SSF2 beta screenshots[1] were uploaded on However, due to the lack of notoriety and distribution of the same, not all the screenshots came be recognized and the leak did not spread.


Battles take place on top of the ND-03 BlueShark submarine. Players fight on the husk of the submarine. The form is rather simple: a prolonged platforms with two edges on the side and a conning tower in the middle. The left portion is a bit slanted downwards.

The stage is unique in the sense that it is an underwater stage, which makes characters jump higher and fall slower. This can be disabled by using the hazard switch, which makes the physics normal like the other stages.


  • The main music track is Steel Diver Theme, a techno remix of the title theme from Steel Diver.

Tournament Legality

This stage is banned from competitive play. While there are no major issues, the center raised bit divides the stage into two and has two small walls allowing for infinites. This has allowed the community to decide it should be banned.

The Steel Divers are a naval task force in the Steel Diver games assigned to combat a power-hungry nation bent on conquest. While a wide number of vessels are under their command for the player to control, the particular model used for the stage in SSF2 is the ND-03 BlueShark, a mid-range, all-purpose sub with balanced attributes. In the original Steel Diver, it is one of three submarines available and uniquely features two torpedoes and a limited pitch wheel. It is also available in the Premium version of Steel Diver: Sub Wars.
