If you need more live-action Master Chief in your life after the Halo 4 launch trailer reveal, the third episode of Forward Unto Dawn is here to help you - albeit with only a tiny bit more Chief. If you've not been keeping up with Machinima's tie-in series, you can check out the first and second episodes here on Joystiq. As for this episode, things start to get really serious when those ever-daunting words of "this is not a drill" ring through the halls of the Corbulo Academy.
