Each of these two contracts will earn you a Mercenary heavy tank… and one is our first-ever ten-stage contract!
Every team needs its guardians, and completing a contract is a reward-rich way to make sure you’re in command of the right tank for the job.
Starting December 20th, you can earn one of the two tanks below (or even both if you’re ready to test yourself):

When you take on a contract, you get a chance to earn a tank by completing a series of tasks over several stages. You’ll also earn rewards along the way as you complete those tasks.
Here’s what else you should know about contracts:
- You can have only one contract active at a time! Once you’ve signed a contract, choosing a new contract will cause you to lose any progress made on the one you’re currently working toward.
- Certain tasks might have tier or class restrictions, but otherwise, each contract can be completed using either World War II or Cold War tanks. Choose your vehicles wisely!
- You can use Gold to skip certain stages! The buyout amounts for each stage will be listed with the other contract details below. Buyouts will be available for one week after the contract’s end date:
- Slapjack: Buyouts available through February 6th
- The Machine: Buyouts available through July 10th
Time to sign up. Read on for each contract’s details, and then head to the “Contracts” tab in game when you’re ready to get started!
Contract: Slapjack
Stand tall, defender. When you’re in control of Slapjack, you’re in command of a tank with the qualities needed to support your team’s attackers:
- Well-reinforced armor
- Heavy firepower
- Outstanding gun depression
Note: Upon completing the contract, if you already own Slapjack, you’ll receive its value in Silver (3,120,000 Silver) instead.

Contract: The Machine
Ten. That’s the number of stages you’ll need to complete in order to claim this Tier X tank.
We’ve updated The Machine’s contract to satisfy those tankers looking for a true challenge. But don’t worry—you have until July to complete it, and we’ve also increased the rewards you’ll earn in the final stages. For those looking for more Silver, Boosters, and Consumables, this is the place to be.
Oh, and you’ll also happen to earn one of the most formidable Mercenary heavies out there. The top speed, gun handling, and intra-clip reload time make The Machine a punishing tank that’s aptly named.
Note: Upon completing the contract, if you already own The Machine, you’ll receive its value in Silver (10,800,000 Silver) instead.
