Looks like "Call of Duty: Black Ops 3" developer Treyarch has finally confirmed what they have been teasing during the past few months. A new challenge system called Contracts is reportedly coming to the game's multiplayer campaign. It will be accessed via the so-called Black Market. Apart from these, a playable character named Blackjack will also be introduced.

According to Gamespresso, "Call of Duty: Black Ops 3" players will be enjoying a new kind of challenge structure - the Contracts, that is. In order for them to play it, they have to go through the Black Market. As long as they are able to complete challenges (i.e. Daily, Weekly and Mercenary, among others) prior to the expiration of contracts, interesting in-game rewards are also expected to be given.

Finishing Daily Contracts will offer "Call of Duty: Black Ops 3" players some bonus Cryptokeys, which is the game's currency. As for the Weekly Contracts, a larger amount of in-game currency is expected to be acquired.

The most interesting part, according to Movie News Guide, is the playable character Blackjack. However, in order for "Call of Duty: Black Ops 3" fans to play him, they have to dominate the Mercenary Contract. Thus, they have to undergo a series of challenges first before playing the this highly-anticipated character.

Basically, Blackjack is the "Call of Duty: Black Ops 3" Black Market Vendor. He can be equipped with a unique array of abilities as well as personalities. If played via the Rogue mode, the character can steal weapons with each Specialist he kills. If Gambler is chosen, he can effectively gain a random specialist ability - something that can charge faster than what is conventional.

Moreover, Special Contracts are also made available. Playing these contracts will offer "Call of Duty: Black Ops 3" fans free and guaranteed Rare Supply Drops (with 10x drop rate) and a Weapon Bribe. However, this amazing stuff can only be possible once they are able to win at least 75 matches.
