This is in Standard Definition. You can watch in HD also. Thanks Gamtrailers!
Info
Halo 1 pistol is almost back. It is a magnum but has a scope. From the looks of it, it takes headshot to kill a grunt.
Graphics look better.
Only 2 sound suppressed weapons. (SMG and ?)
Special visor lets you do something. Can't hear what he says (fishing, vision, etc?)
Animation is far greater. Brutes look sexy. They die a lot cooler. Armor comes off a lot nicer too.
On your visor, there is a HUD. Compass on the top. Tells you if you're getting closer to something important. Nice touch.
NEW INFO
Brand New Xbox 360 ODST Controller <-Definition of sexy.
