[8] Tancharoen noted the positive fan response and realized the advantage of social networking in helping small-time directors gain a following to take to film studio executives.

[6] He met with Warner Bros. executives, who stopped short of green-lighting a major motion picture, but agreed to fund a web series based on the Mortal Kombat franchise.

[18] Despite the changes, Tancharoen promised fans the web series would be true to the franchise, including the mystical and supernatural elements famous to Mortal Kombat.

Episode three follows suit, but ends with the first hint of supernatural themes when Shang Tsung appears to freeze time to converse with Johnny Cage.

Criticism has been leveled at the production team for abandoning the original real-world approach of Rebirth for Legacy, despite Tancharoen continuously stating that the supernatural elements of Mortal Kombat would be included in the series.

On July 15, 2012, IGN revealed an exclusive video made by Tancharoen directed at fans announcing Season 2, adding that all of the scripts were complete.

On December 3, 2012, it was announced that the second season of the series had begun production in Los Angeles,[21] with the first footage debuting worldwide in a trailer on February 17, 2013 at the Streamy Awards.

[24] On March 31, 2013, a TV spot aired during AMC's Talking Dead for the series – the first time a YouTube channel had bought ad space on television.

[34] On January 13, 2015, martial arts trainer and stunt coordinator Garrett Warren confirmed his involvement in the third season of Mortal Kombat: Legacy, without revealing his role.

Michael Jai White, Jeri Ryan, Matt Mullins and Ian Anthony Dale reprise their roles from Mortal Kombat: Rebirth as Jax, Sonya Blade, Johnny Cage and Scorpion respectively.

[42] Johnson Phan and Fraser Aitcheson replace James Lew and Lateef Crowder to portray Shang Tsung and Baraka respectively.

[44] Episode 4 revealed Aleks Paunovic as Shao Kahn, Jolene Tran as Mileena, Kirby Morrow as King Jerrod, and Beatrice Ilg as Sindel.

The characters of Sub-Zero (Kevan Ohtsji), Sektor (Peter Shinkoda) and Cyrax (Shane Warren Jones) were revealed in the first official trailer released April 11, 2011.

Casper Van Dien replaced Matt Mullins as Johnny Cage, while Cary-Hiroyuki Tagawa, who had played Shang Tsung in the 1995 film, took over the part from Johnson Phan.

Debuting characters included Harry Shum, Jr. as Kuai Liang (Sub-Zero's younger brother), Brian Tee as Liu Kang, Mark Dacascos as Kung Lao, Kim Do Nguyen as Ermac, and Daniel Southworth as Kenshi.

[30][50] Jeri Ryan (Sonya), Michael Jai White (Jax), and Darren Shahlavi (Kano) did not return, nor did their respective characters.

In several tweets in June 2011, Tancharoen stated that the final episode would not be released along the usual pattern of midnight Tuesday morning, but would premiere some time during the 2011 Comic Con event to be held between July 21–24, 2011.

[64] President of Warner Bros. Digital Distribution, Thomas Gewecke, expressed excitement about the first episode and its prospects for future adaptations, saying, "it's an incredibly powerful, strong and well done piece of filmmaking.

[67] IGN described Legacy as the "most elegantly produced web series", giving particular mention to episode one for "effective action sequences and some great cinematography".

[68] It looked favorably upon episode 4 for the first use of "extraordinarily effective" animation and "poetic" voice-over narration, the removal of censorship, the "fascinating character lore and dazzling fantasy [and] a beautifully crafted land of Outworld".

It "allowed the series to broaden its horizons a bit" by creating a likable Johnny Cage, commenting, he "finally lets loose and makes you appreciate the character in a whole new way".

They stated that while the martial arts took a backseat, the drama of Raiden's "Christlike" story was well-executed, giving audiences a reason to identify with his character in a way the franchise has never been able to do.

[75] IGN noted of episode one that the "production values don't seem quite as tight and concise as [Rebirth]" in addition to light story and "flat" editing and performances.

Cheaper make-up, costume effects, and set design due to budgetary constraints, and a short running time were among the other criticisms.
