You earn Warface Dollars (WF$) for every mission you play, irrespective of the game mode selected. As you need this currency to maintain your equipment and buy new items, it's advisable to try and get as much WF$ as possible as you play. There are a number of ways to increase your yield from Co-op missions considerably, even without Boosters, and you can also decrease the repair cost in other game modes. Let's take a look.
Earning more Warface Dollars in Co-op missions
There are two ways to increase your daily Co-op missions WF$ income.
The first one is to use the full potential of the double rewards available for the first completion of any Co-op mission by completing them all. The more difficult ones will also yield more WF$.
The second way is to complete the Commander's Orders for the mission. These vary for each map and change daily, so you should always check what's required of you in order to increase the reward. Each completed order increases the rewards for the whole team by 10% and the maximum number of orders is two. Communicate with your team and make sure everyone does their best to increase the yield for the whole team.
Contracts
This is the Contracts screen. Here you can accept various special assignments for increased rewards. However, you can only take one out of three available, and you must complete it in the given amount of time, otherwise you won't get the reward. Contracts change daily, so keep coming back to get more rewards!
Reducing repair costs
Repair costs can become a significant drain on your currency if you don't keep them in mind while equipping your character for a mission. Weapons and outfits should be selected according to the difficulty of the task ahead of you, it's not worth taking the best gear on easy or normal missions, for example, as the repair costs might exceed your mission income. Always follow the maintenance costs of your items, and only use those you can afford. However, in the Clan Wars mode, you'll always want to gear up with your best equipment to overpower your enemies.
Another way to decrease maintenance costs, and thus increase your WF$ income, is to use rental items as these don't need to be repaired. This doesn't mean you have to pay for the temporary use of certain weapons – there are plenty of opportunities in Warface: Clutch to gain access to temporary items for free, such as various challenges, special seasonal events, daily login bonuses and rank-up rewards. Who knows – maybe you'll even discover your new favourite gun this way?
