Halo Reach MP Trailer Details

I've watched the trailer in more detail and here some things I've noticed:

• 0:07 - Scorpion gunner fully exposed like Wraith gunner
• 0:09 - Uppercut finishing move, suspect this is just built into the melee function (mentioned on bnet) like the assassination animation shown later
• 0:10 - Glow shields (mentioned on bnet)...shields glow with an outline and then "explode" when gone showing when to get a headshot easily
• 0:11 - Dive roll...this looks brand new, some kind of Gears of War mechanism maybe
• 0:14 - "Loadouts" This is the first appearance of the ZOMG jetpack. Calling it "loadouts" implies you can choose this at spawn, interesting. More subtly, the Spartan running through the foreground also has active camo.
• 0:17 - "First Strike" is a new medal. Appears has an orange upside-down pentagon with a skull in it. Announcer also displays kills "with grenades" now.
• 0:20 - A new HUD element above the radar shows what must be the jetpack "fuel" remaining.
• 0:22 - What appears to be a ghost splatter is actually not. The ghost explodes afterwards. The HUD special equipment shows a lock, maybe that has something to do with it?
• 0:25 - "Pull" and "Headshot" medals. Pull medal implies kill for somebody in the air based on this kill and how the medal looks like a jetpack.
• 0:25 - Green and yellow multi-colored armor.
• 0:27 - First look at what is presumably the DMR (BR replacement). Looks seksi.
• 0:28 - Rocket kill in the air. This is almost impossible with today's non-tracking dumb rockets. If we presume there's a reason that they've chosen to show this, maybe rockets track flying people now?
• 0:29 - Active camo armor being shown with HUD element.
• 0:30 - Sniper targeting reticle turns red and then suddenly gets huge when bullet strikes. Unclear if this is to indicate headshot available, or because reticle expands to cover shield explosion.
• 0:32 - Assassination animation. This one appears to be with a knife, though it's pretty homoerotic in the showers there.
• 0:34 - Two more assassinations here, these climbing up on top like a jockey.
• 0:41 - "Invasion" Assuming this is a new game type where one team storms a base or something.
• 0:45 - Some kind of new gun that has a targeting reticle similar to the gauss cannon.
• 0:46 - Sniping in more detail, again with the expanding reticle. This time much more strongly suggests headshot indicator.
• 0:47 - New weapon, looks like a Fuel Rod cannon, but has "energy" instead of rounds. Appears to be 6-7 points per shot, so in total maybe 15 shots. Appears to have a track locking feature. 3 shot warthog pwn.
  
• 0:51 - Dive roll shown in more detail this time
• 0:51 - "Headhunter" Maybe some kind of skull that can be enabled? A bunch of flaming skulls explode out of the dead guy. Could be a human equivalent of Grunt Birthday Party.
• 0:53 - Again showing the changing reticle size, this time on a DMR. Headshot results in flaming skulls.
• 0:57 - "Active roster" - Have no idea what this means
• 1:04 - Gauss cannon thing appears again, with the reload animation showing a shell being put into the chamber. Also notice the lightning bolt HUD element for special equipment. Maybe sprint upgrade?
• 1:06 - "Spartans vs Elites" - Have to assume this is a new self-explanatory game mode. So far have only seen Elites being able to dive roll.
• 1:09 - Equipment HUD element looks like a targeting reticle, dunno what it is. Rocket destroys "generator" implying some new gametype.
• 1:14 - "The Arena" - Dunno what this is, maybe a map?
• 1:16 - What I previously described as the "rail gun" appears to be new Covenant beam rifle maybe? The beam trail is significantly more pronounced everywhere it appears, and actually tracks the target being hit here for 3 or 4 steps.
• 1:17 - New "Revenge!" medal. Red skull on upside down triangle.

All in all, the game looks generally gorgeous. Very excited. Two months left.
