Mortal Kombat X recently released its final planned downloadable content (DLC) pack which included the character Tremor. Now, many Mortal Kombat X fans think there is more DLC coming, Venture Capital Post reports.

With each DLC release for Mortal Kombat X, a new playable character was added to the roster. A season pass called the Kombat Pack included all of the DLC characters, but now it is being referred to as Kombat Pack 1.

The characters that were added with the DLC packs were Jason Voorhees, Freddy Krueger, The Predator and Tremor.

Mortal Kombat creator Ed Boon teased that there could be more characters coming into the game, according to Playstation Lifestyle. 

Mortal Kombat X has been an extremely popular game, and there is still plenty of room for more characters. Currently, Rain and Noob are not playable in the game after appearing in other Mortal Kombat games.

Mortal Kombat X could also continue to bring characters in from movies or comic books like they did with Jason, Freddy Krueger and The Predator.

With a delayed release for Xbox 360 and Playstation 3, Mortal Kombat X could celebrate its release with some more DLC packs. The Kombat Pack 1 season pass sold for $29.99. If Mortal Kombat X decides to release a second Kombat Pack, it will probably sell for that same price.

Fans of Mortal Kombat X should keep an eye on Boon's tweets on Twitter. In the past, he has revealed the characters that ended up appearing in the game.

There are also live game streams. In these streams, Mortal Kombat X's developer NetherRealm developers reveals hints on new characters, special moves and features. If more DLC is coming for Mortal Kombat X, it will likely be previewed on a live stream.
