Modern Warfare 2 Beta Unlocks and Rewards

The Call of Duty franchise has had its fair share of game-breaking bugs across the years, from glitching into buildings to the notorious invincibility glitch from Warzone. That's one reason why Activision has focused on launching the Beta version of the game before a full release. Through the Beta, the developers can pinpoint bugs and other exploits they may have overlooked. For example, players found a serious game-breaking bug in Call of Duty: Modern Warfare 2 that allowed them to see through smoke with a sniper optic.
