Is Mortal Kombat 11's Director Teasing a New DLC Announcement? ✖ Mortal Kombat 11 players think creative director Ed Boon may be teasing the announcement of further DLC characters. A couple of months ago, NetherRealm Studios and WB Games released Mortal Kombat 11 Ultimate, which added Mileena, Rain, and Rambo to MK11's already large and impressive roster. And now, it looks like NetherRealm Studios may be poised to add even more characters to the fold. While NRS and WB Games haven't announced new DLC characters, rumors and leaks have been suggesting that the game is still getting at least a few more fighters. And now players think Boon is teasing these fighters, or at the very least, some type of announcement.
