Mortal Kombat 1 has been busy since its launch releasing new DLC fighters as part of the Kombat Pack, and the latest one will be arriving next week.
On social media, Warner Bros. has confirmed DC's Peacemaker will be made available in "early access" on Febuary 28:
"Peacemaker is preparing for his arrival in the New Era. Early access will be available on February 28, along with the arrival of the new season around the same time. Details on both will be coming later this month. #MK1 @MortalKombat"
As noted, more details about this character will be shared later on in the month, alongside information about the new season. Peacemaker follows on the addition of Quan-Chi last December.
