This is taken from gamereactor.eu:
"First up, the Black Market is heading to Titanfall, and soon players will be able to pick up packs of Burn Cards and Titan Insignias with credits earned playing the game. We'll be able to buy themed packs, or take our chances with the standard pack, as well as add new insignias.
To facilitate the Black Market, Respawn are introducing an in-game currency. Credits will be given for finishing matches (and more for winning, naturally), daily challenges, selling burn cards, and a percentage of a player's XP will turn into Credits at level 50. The new feature will be available to players who have passed level 11.
Designer David Shaver signed off the update with reassurances that while an in-game currency is being added, players will not be subjected to microtransactions:
With the introduction of an in-game currency, some may worry that the next step is that we will let players spend real-world money to get an edge in the game. We have stated several times that Titanfall will not have micro-transactions. Fear not, for we plan to keep that promise - NO MICROTRANSACTIONS! The only way to get Credits is by playing the game!"
THIS IS AWESOME!!! ... that's all I have to say.
