Contracts

Contracts are a new multiplayer feature in Call of Duty: Black Ops.

Mechanics
Contracts are available to purchase with CoD Points. Different contracts will have different goals, such as achieving a certain number of killstreak rewards or getting a certain amount of kills with a specific weapon. Completing a contract will yield more CoD Points than the player paid for the contract itself. The higher difficulty of the contract, the higher payout upon completion. This may have also been a way to prevent hacks such as 10th Prestige lobbies. The old Challenges system will still be in place, so contracts are just an addition.

It is also important to note that the contracts do in fact expire. Once the player has accepted the contract, they have a certain amount of time to fulfill this contract.

It is also mentioned that there will be a different set of contracts every day for players to fulfill, so players must do contracts while they are there or they will be gone the next day.

The Mercenary Contract, "SPAS Cruelty", for example, is bought for 50 CoD Points and requires the player to get 25 kills with the SPAS in 40-minutes of time alive in-game. The reward for completing this particular Contract is 250 CoD Points.
