*****UPDATE*****
This no longer works since they patched the game. Sorry.

This video for Rainbow Six Vegas 2 is for all the achievement junkies out there and for people like me under normal circumstances would never level up due to not playing multiplayer a lot. This video is done by the folks over at Next Gen Walkthroughs. This site is where I get a lot of my game help whenever I get stuck on games. They do walkthroughs for games like COD4, Gears of War, Halo 3, and a lot of other games. They take video footage of the best paths that they have found to get through games on the hardest difficulty. Veteran for COD4, Insane for Gears and Legendary for H3. In any case, this is a video showing how to get easy experience points so you can level up in no time on R6V2. There might be better ways to get to Elite in multiplayer but this is a pretty good way to unlock all of the A.C.E.S. classes which in turn unlocks the “Weapon Collector” achievement. Something the video doesnt mention, is that if you wait until they get on the turret before you shoot them, then you get points toward the “Assault” category. If you walk up close to them and shoot them with the shotgun or the Desert Eagle, you get points towards the “CQB” category. Enjoy.
