Respawn has announced plans to introduce an in-game currency to Titanfall that players can use to purchase new insignias and Burn Cards - but has pledged to stick to its original promise of keeping microtransactions out of the game.

Due to be introduced with Update 5, credits will be awarded to players for completing matches, winning matches, their first victory of the day, completing Daily Challenges and selling Burn Cards. Once players hit level 50, a percentage of XP earned will also be converted into credits.

Credits can then be spent in the game's new Black Market, an in-game store that will sell packs of Burn Cards focused around specific themes and new insignias for your Titan.

"The primary goal of Burn Card packs is to give you more choice in the kinds of Burn Cards you get and to fit different play styles," says Respawn. "The Cards you get are random, but you get a set of Cards you know you will enjoy using. Do you like using Ordnance more than Tactical Abilities? Sell the Ability Cards for Credits and buy an Ordnance Pack!"

The Black Market will become available once players reach level 11 and remain available even after they regenerate.

"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," Respawn adds. "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!"

Update 5 - and the game's upcoming Frontier's Edge expansion pack - rolls out next Thursday, July 31.
