That video clip was copied from "Call of Duty 4" on the XBox360. It is an awesome game. In that part of the game you get to be the gunner in an AC-130, it is really fun!
I especially like the graphics when you are crawling on your belly in your ghillie suite with your sniper rifle in the tall grass, trying to make it through the on coming tanks and ground personnel. It looks cool when you catch up to the sergeant and can see his boots on the ground in front of you. A little bit after that you have to crawl under a bunch of trucks to make it the other side of the court yard. Then the trucks start moving above you. I haven't made up my mind which weapon I like the best yet, they are all cool and have there usefulness. gun)
Halo3 has a cool sniper rifle and scope too, too bad they haven't included bullet trajectories and wind to make a bit more realistic.
Sometimes it is good to have young boys to buy toys for.
Too bad I will never be able to afford a high def TV with this dang rifle habit, the game is even better in 1080p …
