Harley Quinn in "Injustice 2" showing the ability to Transform Gear. These will be the in-game currency that gamers will use to buy cosmetic features for their characters. That changed today with the introduction of Source Crystals, a real-money resource which will be one of the game's main forms of currency for changing the way your character looks. These upgrades do not fall into the Gear category, though, and players won't be able to pay to increase character stats.
The announcement from WB Games assured players that Injustice 2 will not be pay-to-win, as these gear choices (which include transmogrification, shaders, and legendary skins with no stat bonuses) will not have any effect on how your character plays.
If that's not clear, the developer reiterated that the premium character skins won't have any advantages in terms of gameplay-they're basically just there to give your character a different shade and look.
If you reach level 20 for a character, you can use Source Crystals to save time and level up another character to Level 20 too. Source Crystals can only be bought from the PSN and Xbox One stores and cannot be earned through playing.
Here's a new Injustice 2 video showing off the latest addition to the roster, Firestorm, who was announced earlier this week.
It's possible that NetherRealm will reveal pricing for Source Crystals soon since the "Injustice 2" director, Ed Boon, has already teased a "more aggressive" approach to DLCs, as pointed out by Game Rant.
There's still 14 unannounced characters in the Injustice 2 roster, and the next character reveal is scheduled for Thursday, March 23.
