Game Informer - 9.25/10 - Mortal Kombat X is a fantastic successor in every sense. The mechanics may be similar to 2011’s strong release, but with so many new modes and features permeating every part of the experience, it’s a worthy upgrade. Mortal Kombat X is more than the continuation of NetherRealm’s successful vision for the franchise; it’s one of the best fighting games in years.
The Escapist - 4.5/5 - Mortal Kombat X offers the best story mode I've ever personally seen in a fighting game. Its cohesive plot and extended cinematics makes you feel much more like a participant in a film than a player on the couch. The fighting is frantic, fluid, and dynamic, with the glorious goriness of the X-Ray moves often turning the tides of battle. An absolute must for franchise fans, and a really stellar bet for general fighting game fans, even those who just appreciate a good story will find a lot to love in Mortal Kombat X.
EGM - 7.5/10 - Mortal Kombat X feels, in many ways, like one step forward and two steps back. I can’t get over the lack of depth when it came to Story mode, and the fighter variations aren’t as interesting as I’d hoped. However, once I finally found my favorites, the actual fighting still felt great. And with the Living Towers promising to keep the game perpetually fresh, I found there’s still plenty here to keep me coming back for more in the future.
Gaming Revolution - 4/5 - Although some of its content feels truncated, purposefully or otherwise, Mortal Kombat X lays a solid foundation for the series for this console generation. The new cast of characters feel a tad callow, but they fit reasonably well with their more iconic brethren. Both the integrated gameplay and the polished presentation set a high standard for the fighting genre, and the replayability of the towers system along with the dangling carrots in the revamped Krypt will ensure that Mortal Kombat fans have plenty to sink their teeth into. In fact, it's roasty-toasty.
USgamer - 4/5 - Mortal Kombat X comes packed with a ton of content. Admittedly, many of the extras (concept art, alternate costumes) are unlocked in the Krypt using in-game currency, but despite those conditions this is easily the most enjoyable Mortal Kombat title to date. Even with its shortcomings (a brief story mode, imperfect net code, missing characters), players would be hard-pressed to say MKX isn't the best Mortal Kombat has to offer. Even little details such as the dialogue between characters, unique to each pairing, add quite a bit to the experience. In all, it's a must-have title for any MK fan. On top of that, it makes for a solid addition to the competitive scene and should enjoy a long tournament life for competitive players.
GamesRadar+ - 3.5/5 - As a whole, Mortal Kombat X is a rock-solid fighting game that owes a lot to the power of its presentation. The story mode is unparalleled in terms of sheer entertainment, but MKX has a way to go in terms of teaching the player how to get the most out of its core systems. Once you've wrapped your head around the many variations and found some actual people to play against, the blisteringly fast back-and-forth matches really start to open up. If you're not willing to make the commitment to seeking out challengers and learning beyond the basics, though, this fighter definitely has a shorter life expectancy.
Hardcore Gamer - 4/5 - 2011’s Mortal Kombat reinvigorated the franchise by taking it back to its roots, retelling the story with a slight variation. Mortal Kombat X goes a step further and wades into uncharted territory with great results. Not only is this the highest quality story NetherRealm has ever put together, it’s perhaps the best fighting game story ever. Character Variations aren’t the game-changer NetherRealm was hoping for, but do little to detract from how good the core gameplay mechanics already are. Deep enough to attract competitive players, yet simple enough for newcomers to pick up and play, there’s no denying that Mortal Kombat X has a lot of meaningful kontent. Mortal Kombat X is not only a great Mortal Kombat game, it’s simply a great game.
VideoGamer - 8/10 - Overall, however, Mortal Kombat X is the most entertaining fighting game on next-gen. It’s bonkers in the best possible way, serving up some eye-watering kills (Cassie Cage’s X-Ray move will make every man wince, every time) and entertaining matches that don’t require great skill to create. Depth lies in learning each character as the story introduces them, which forms a springboard to use them in other modes that surround it. Story mode is engaging enough to keep you plodding through in short bursts, the Krypt offers content that will make you want to earn the Koins to unlock everything, and all other modes change up the combat enough to keep you interested. This is the best Mortal Kombat game, and also the most hilariously brutal.
Digital Trends - 4.5/5 - Despite the extreme and often cringe-worthy violence, Mortal Kombat X is quite beautiful in its own way; like visiting a museum exhibit on the human body and all the ways it can be destroyed. And like a museum, there’s plenty to see and do here, including a surprisingly intimate story, one-on-one battles, endless challenges, and a competitive, socially-connected metagame.
Metro Game Central - 8/10 - Surprisingly generous is not a phrase that gets used much nowadays but in terms of the number of characters, modes, and unlockables Mortal Kombat X exceeds expectations. And more importantly it’s a really fun, and amusingly grotesque, fighting game. It’s still not the deepest fighter around but that’s not what’s its aiming for. Instead, there are several things it does better than its rivals and even just being identifiably different is no mean achievement for such a crowded genre.
