Alternate Costumes
Play your favorite characters not only in the costumes that come in the Mortal Kombat Unchained story arch, but in some of your favorite classic outfits as well.
Alternate costumes can be unlocked in the Krypt by unlocking them in Koffins. When you've unlocked an alternative costume, it won̵7;t show up in the character menu. Activate an alternate costume by going to the character select screen before fighting and selecting the character by pressing start instead of ̶0;X.̶1; Once the fight begins you will see the character in his alternate costume. Some costumes available include Sub-Zero in his classic outfit, Scorpion without his mask and Baraka in his Tarkatan warrior costume.
Finding Fujin, Reptile and Kira
Unlock these characters through the Konquest role playing game included as an addition to the fighting game. Fujin is located in Earthrealm section E-4. Simply look for the man in the multicolor coat and enjoy.
Reptile is a little more difficult. Also in E-4, but in Outrealm, Reptile is obtained by beating him in combat on his home ground in the forests.
Unlocking Kira in Konquest requires a bit of timing. Wait until game time is close to 7 p.m. then go to the beach in Earthrealm section H-2. The second house will have a gold treasure chest. This treasure chest unlocks Kira.
Living Liu Kang
Followers of the Mortal Kombat storyline will know that Liu Kang was killed by Shang Tsung in Mortal Kombat Deadly alliance, but resurrected as a zombie. If you don̵7;t like zombie Liu Kang, you can get the original back by beating the fighting mode with the zombie version. This will enable you to select regular Liu Kang the same way you would select an alternate costume.
800 Koins from Sonya
Sonya appears in Konquest in Outworld at position A-8 only from 6-7 p.m. game time. Speak to her there and she will give you 800 Sapphire Koins.
The Frost Fatality
Not widely known, Frost has a fatality in Mortal Kombat: Unchained. Achieve the Frost fatality by standing about three steps back from the opponent in the ̶0;Finish Him̶1; screen. Once in position, press forward, back, up, down and square.
Unlocking Onaga
In Mortal Kombat: Unchained, you can play as the Dragon King of Outworld: Onaga. The most time-consuming trick in the game, this requires that you beat arcade mode with all characters or finish endurance mode with all characters.
