Samurai Gunn (from boy genius Beau Blyth) has been flying under the radar for a while, but now it's available for the entire world to experience. The frantically-paced Bushido brawler released on Steam and the Humble Store today without telling anyone it was coming.
The fact that it stealthily released isn't the sticking point, though. Samurai Gunn has seriously impressed in its pre-release builds. In fact, it was my favorite game that I played at PAX Prime. This is one title that you'll want to make a point of looking into.
