New Halo 4 Live Action Trailer W/ Gameplay Released at E3!

Yesterday, at the 2012 E3 conference, Microsoft released an all new Halo 4 live action trailer with about five minutes of game play footage and after viewing it, oh mi god am I excited. There are two videos. One that is shorter and does not have as much campaign footage and does not show the live action trailer but does have multi-player footage and one video that is seven minutes with the live action and only campaign footage The trailer shows UNSC marines lined up listening to a speech while the video flashes forward to their ship being infected by an unknown virus that takes over. It finally then jumps to Master Chief. The man of the hour and as he watches the UNSC ship (That resembles the Pillar of Autumn) seem to come through a portal of some sort (Possible a time portal) and fly over him with obvious complications. Chief watches it fly off in the distance as he's surrounded by nature. Obviously, he has progressed and landed on this turf since we last saw him in the Halo 4 teaser that was released last year. Will the game reveal what happened between that time gap? I hope to god they do.

If you read my earlier post about Halo 4, then I must make a correction. I was under the influence that the Covenant were gone but after watching the footage, there is a scene with two grunts, an elite and a jackal. So yes. The humans most hated enemy is back. As the elite charges you, it seems to be shot with an orange ray that disintegrates it in it's own footsteps. That is where the new alien species is introduced. They look to have a mix of organic and technology base to them and as Chief shoots some, they self destruct where others have the ability to teleport. He even does hand to hand combat at one point which is extremely bad-ass and when picking up one of the foreign guns, it seems to recreate and modify itself at the sense of his touch.
At the end of the video, a strange red symbol appears with the words "An Ancient Evil Awakens". My assumption? Forerunners. Cortana even mentions them at one point when discussing the aliens. So yes, mysteries of the Halo universe will be revealed in this new trilogy.
