Call of Duty: Modern Warfare 2 Beta-- Best Perks And How They Work

gamespot.com:

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.

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.

While it might seem like a bummer to not have all your perks for the start of the match, you can acquire your perks earlier than the standard earn times of four and eight minutes. You just need to score some kills or play the objective of whatever mode you're in, as every 10 points you earn in your match will shave a second off of the timer.

It's important to consider your playstyle when choosing perks for your custom packs. If you're an aggressive player, you might want Double Time and Overkill for your base perks with Fast Hands and Bird's-Eye for the bonus and ultimate perks. This will let you speed around the map with two primary weapons, give fast reload and weapon swap, and you'll get enemies marked on your map.
