The Ninjas -- they are back again. And this time they're 8-bit and oh, so awesome retro-badass. Hit up YouTube, unbox that Galaxy Nexus in style, and vanquish the hoards of enemy ninja -- no match for your lighting button bashing. This is how classic gaming should be. Just make sure you've got at least 15 minutes to spare, and your boss isn't around, before you click the link, OK?
