The whole "the guns are the stars" thing makes a lot of sense after watching those, the detail in the gun textures, firing animations, sounds etc etc, is fantastic.
As a single player game though I hope they have some kind of soundtrack for it, adds so much to the atmosphere.
Reminds me of goldeneye other than the lack of a backing track, nice straight forward action, dont have to put too much thought into getting from A to B, just have to be quick on the trigger. Should be cool.
