Native Development Kit introduced back in the Cupcake days never got a ton of attention despite the subtle hints that it'd give devs the low-level access they needed to create killer, graphically rich, immersive environments ready to compete with pretty much any other gaming device you could shove in your pocket. Of course, at the time, every phone in the market was running an older, slower ARM11 core -- so maybe the new generation of ARMv7-based devices we've got hanging around now like the Nexus One and Droid are the catalysts we need to get this party started in earnest. Japan's HyperDevbox studio has just shared the news that its ExZeus Arcade shooter makes full use of the NDK, your microSD card, and a custom sound driver to bring a gaming experience hotter than pretty much anything we've seen on Android thus far; the only catch is that you need Android 2.0 or up and a phone with a dedicated GPU to get it going. It's available now in the Market for a seemingly reasonable $3.99 -- and let's let this serve as a reminder to other game studios that they've got the tools and the horsepower to rock Android hard. Follow the break for video of ExZeus in action.
