Leveling and Killstreaks
Challenges and Contracts
During multiplayer, you will only have access to a hand full of weapons and items from the start. As you play matches and gain kills you will earn Experiences that will unlock new modes and moves. You can also gain Call of Duty points to buy all sorts of gear, perks, killstreaks, and playercards. You can even wager these points against other players, gambling for huge gains or losses.
Among the fastest ways of gain Experience and CoD Points early on is to complete Challenges and Contracts. Challenges can be completed at any time and will continue recording progress as you play. They have simple tasks such as scoring enough kills or using a curtained type of weapons. Unlike Challenges, Contracts need to be bought with CoD. You only have a set amount of time before these Contracts expire, ranging from less than an hour to several hours. If you fail to complete these contracts you may need to wait up to 24 hours before renewing them. Still, the rewards are worth with if you can complete these tasks in time.
Killstreaks
A huge means of aiding your team and crippling your enemy (thus granting more Experience and CoD Points) are Killstreaks. As you gain between 3 through 11 kills in a row you can deploy extra rewards to help the tides of war. During on-line multiplayer, each of the different Killstreaks will cost CoD points to equip and you'll only be to have three at a time.
