Infinity Ward is wrapping up a PlayStation-exclusive first weekend of Call of Duty: Modern Warfare 2's multiplayer beta. The crossplay beta weekend is coming up, and we're highlighting all the perks available in the game. Modern Warfare 2 makes some pretty significant changes to Call of Duty's perk system, so we're going to break down everything you need to know about using perks this year.

How perks work in Modern Warfare 2

Call of Duty: Modern Warfare 2 features a mostly familiar list of multiplayer perks that longtime fans will recognize, and there are a few new perks to discuss as well. However, perks work a bit differently in Modern Warfare 2.

In Modern Warfare 2, perks come in "packs" of four. You can customize which perks you want within your customizable pack, but you'll only have two "base" perks active at the start of the match, while a bonus and an ultimate perk are both earned during the course of the match. The bonus perk is earned four minutes into the match, and the ultimate is earned eight minutes into the match.
