I didn't see this posted anywhere else, so I thought I would share this info. If you could care less about achievements, have never played the original Rainbow Six: Vegas, or if you have already loaded this game onto your profile (ie. put it in your Xbox 360), then you can go ahead and ignore this thread.

Unfortunately Ubisoft has accidentally glitched one of their achievements by rewarding those that completed the previous RB6V on realistic difficulty and/or reached the rank of elite. The 'prize pack' that they provide, automatically promotes you to the rank of Specialist, along with giving you some extra XP and gear. Normally this would be a good thing, but this promotion forces the player to skip the rank of Private First Class, which turns out to be an achievement. The odd thing is, is that this glitch seems to affect ANYONE who has played the previous Rainbow Six, and not just those that have reached the 'prize pack' specifications.

In conclusion, if you have played the previous Rainbow Six: Vegas, and still want one of the easiest achievements in the game, then I would suggest you follow the instructions in the link below.

Rainbow Six Vegas 2 hit store shelves today. If you bought the game at Best Buy you got a sticker on the outside of your case that contained a code to unlock an exclusive Best Buy gun.

The code can be used by anyone regardless of if you bought the game at Best Buy or not. This is not an XBOX Live Marketplace code.

FREE GUN: At the main menu enter the follow button commands at the Main Menu of Rainbow Six Vegas 2:

(Hold RB) Down, Down, Up, Up, X, B, X, B, Y, Up, Up, Y

FREE MAP (thanks Midnight): Got my copy from Gamestop. It contains instructions to unlock a "Comcast Optimized Map.":

From main menu select "extras"
Select "comcast gift"
Enter "COMCAST FASTER"

Who else is purchasing this game? I see that it supports up to 10 persons in online co-op.
