Preset Classes for Multiplayer in Modern Warfare 2
There are five preset classes available when playing multiplayer mode in Modern Warfare 2. These classes give players access to weapons and perks that they may not yet have unlocked. Until the weapon or perk is unlocked, play will not count towards any associated challenges. For instance, if a player is using the Grenadier class before they have unlocked the M203 grenade launcher, kills made with the grenade launcher will not count towards unlocking the masterkey shotgun attachment, though they will count as FAMAS kills towards unlocking the M203 attachment. Once the M203 attachment is unlocked, further kills with it would count towards unlocking the shotgun attachment. Similarly, a player will have use of the listed deathstreaks and perks, like Scavenger, but until the player reaches level 13 to unlock Scavenger, no progress will be made towards the Scavenger challenges. Furthermore, when a Pro version of a perk is unlocked, it is also applied to the preset classes.
