The people behind the popular mech FPS game, Titanfall, are planning something special for the next update, called simply Update 5. They're introducing what has been called a 'black market currency' into the game, which is really a system for earning points.
The points can be earned in-game through completing certain set challenges or selling on unused burn cards, and can then be used to trade for burn cards which might be a better fit for your play style. The thing that is most obvious at a glance though is that this is a currency that can only be earned in the game; there is currently no plans to make the currency purchasable in any amounts for a sum of real-life money.
The update will also include Daily Challenges, possibly as the ones set up to earn players the new currency. The PC version is also getting some better support for multiple GPUs and the upcoming DLC Frontier's Edge will introduce three new maps to the game.
There's currently no ETA for Update 5, but patch notes are due to be released some time next week.
