Markus "Notch" Persson has been pretty forthcoming with the development progress on his follow-up to Minecraft, the space-based adventure 0x10c. We've seen some screens and a fan-made trailer, but today we have some early prototype footage. Yes, the above video of 0x10c is meant more as a test than your usual gameplay trailer – Notch is testing physics, bobbing and guns in this early build. Still, it's great to see he's making progress despite recent hiccups.
