This week 3D Gunstar Heroes hits the 3DS eShop in Japan, and it's bringing with it a host of new features.

In addition to being in stereoscopic 3D and offering the usual range of screen filters, the game will also include a brand-new "All Spec" mode which grants immediate access to all 14 weapons available in the game. Mega Life mode doubles the number of lives you have in stock, making it easier to face the game's incredible boss battles.

Local co-op play is also supported, but both players will need a copy of the game on their 3DS console. You'll also be able to toggle between the Japanese and "overseas" versions of the game.
