Here's our very first video in our new series LOCK AND LOAD which we are working on with the team over at XBLGAMERHUB. We are going to go through the first mission on Halo 4.

 The level starts with John being awakened by Cortana due to some unknown activity aboard the Forward Unto Dawn. John is sent to investigate. As he looks around he discovers Covenant searching the ship and after dispatching them he finds out that there is an entire Covenant fleet assaulting and that the Dawn is being pulled inside a forerunner planet Requiem. Cortana directs Chief to activate the Hyperion missiles to get rid of the Covenant Cruiser, John does so but has to fire them manually when they become jammed. The Cruiser gets destroyed and John runs for the escape pods with Cortana giving direction, as the Dawn is still being pulled inside Requiem. But John doesn't make it and is sucked into Requiem along with the rest of the UNSC Foward Unto Dawn.
