Call of Duty: Modern Warfare 2 -- Beta Killstreak Guide

gamespot.com:

Call of Duty: Modern Warfare 2 is wrapping up a PlayStation-exclusive first weekend of the game's multiplayer beta. The crossplay beta weekend is coming up, and we're highlighting all the killstreaks in Modern Warfare 2, including one really exciting change to how you earn them. Here's everything you need to know about killstreaks, and we give a few recommendations for those new to the game.

Almost all of Modern Warfare 2's killstreaks are options we've seen in the past, but one great change this year is the option to choose if you want your streaks to be earned as scorestreaks or killstreaks. The choice isn't tied to a perk or any disadvantage; you can simply pick how you want to earn the streaks. For example, a UAV will require you to achieve a four killstreak, or it can be earned with a score of 500 points. To choose between killstreak or score streak, you'll simply want to press the right trigger (R2) on the killstreak menu to toggle between the two options.

However, this new choice doesn't work like some scorestreak options in past Call of Duty games, where you keep your scorestreak progress even after death. In Modern Warfare 2, if you die, your score progress is wiped, and you must start accumulating the scorestreak points all over again. Additionally, on the killstreak side, it's important to note that Modern Warfare 2's killstreaks do not stack, which means that kills earned by your killstreaks will not count toward your active killstreak progress.

The only streak new on the list is the S.A.E. killstreak, which is described as a trio of jets that release aerial explosives onto specified targets. This seems to work like a more powerful version of the Precision Airstrike, and it only costs 125 score or one kill
