We already know about four characters coming to Mortal Kombat X as downloadable content, and it sounds like even more may be on the way.

Series creator Ed Boon, never one to shy away from teasing things on Twitter, recently responded to a question asking about certain characters being added to the game. Specifically, he was asked whether we'll see non-playable characters from the game's story mode made accessible to players. To this, Boonresponded, "[You] mean like a 'Story Pack'?"

Rain in 2011's Mortal Kombat

There are a number of characters who have been playable in previous Mortal Kombat games, like Baraka, Rain, and Sindel, who are not only present in the game's story mode, but are challengers that you'll have to fight. Despite this, they aren't playable, although a modder recently got these characters working on PC to some extent.

Boon's tease didn't make it explicitly clear that a Story Pack would be released as premium DLC, although after learning that microtransactions were available for the game's easy Fatalities, it's hard to blame anyone for making that assumption.

Still, developer NetherRealm Studios and publisher Warner Bros. aren't entirely averse to giving stuff away; the most recent patch added a free costume, something that will be the case with every patch going forward, according to a tweet from Boon.

More and more DLC. Shame.

i have said this before buying a fighting or racing game should be avoided. instead we should go retro.
those games are not complete anymore. literally they aint. you may think im exagerating but this is basically

the game: evolved

There is a difference though.  These games are a lot more in depth and a lot more work goes into them than old games. Not to mention they cost a lot more to make.  Comparing MK1 to MKX and its night and day.  Shows how far games has come more than anything

So glad I passed on this.

You missed out. The game's amazing.

They should be free. They are already in the game and have there moveset. Will wait for the full edition releasing later in the year now.

THeyre not finished as known from the mod.  Very limited movesets right now

As expected, these characters weren't ready in time so they didn't make the launch cut. All one has to do is look at the development of other fighters like Killer Instinct, Tekken 7, Smash and Street Fighter V to have an idea of how this works. The game is already complete without them and no bitching is necessary in my opinion. In the PS2 era you'd have to wait until Mortal Kombat XI to have these characters. By all means skip the DLC or the game entirely if this rubs you the wrong way.

Exactly why months ago I decided to wait for 2016/2017 and the "Komplete" version with everything.

Become the norm for fighting games, what really annoys me is releasing DLC after the third and "final" expanded version is out....looking at you DoA 5.
