Killstreaks are a feature in the game Modern Warfare that allow players to earn points by killing enemies with specific weapons. The more kills a player makes, the more points they earn. There are three types of Killstreaks: Assault, Support, and Sniper. Assault Killstreaks award players with points for killing enemies with a specific type of weapon. This includes pistols, shotguns, and rifles. Support Killstreaks award players with points for killing enemies with a specific type of vehicle or object. This includes tanks, planes, and boats. Sniper Killstreaks award players with points for killing enemies using a specific type of weapon or object. This includes snipers on buildings or in vehicles. To earn points for any kill streak, players must first complete at least one mission in that streak without dying. After completing one mission in the streak, they can start earning rewards for that mission such as XP and money. Players can also exchange XP and money for new weapons and vehicles in the game’s multiplayer mode.
