Everyone is so hyped up about unlocking the "Super Unlockable" characters, problem is, they probably all ready are unlocked if you've found Raiden, Liu Kang, and Shujinko. In Mortal Kombat: Deadly Alliance: Nitara, Drahmin, Hsu Hao, Frost, Jax, Kitana, Raiden, Reptile, and Cyrax were unlockable characters. You fought, got koins, and unlocked them in the Krypt. This principle was modified a bit for Mortal Kombat: Deception. You play Konquest mode, run around looking for chests at certain points in the day, earn money, and unlock them in the Krypt. Havik, Hotaru, Kenshi, Kira, Li Mei, Sindel, and Tanya can all be unlocked without completing Konquest mode (Jade and Noob - Smoke can be unlocked without even going into Konquest mode...you just buy their koffin). Liu Kang, Raiden, and Shujinko, however, you have to beat the Konquest game -- and have to play it even after you beat it -- in order to even remotely get a chance of looking at these three people.
I hate to say it, but I think Liu Kang, Raiden, and Shujinko are the Super Unlockables. 'Cos you have to go to a great length to play these people -- great lengths usually mean extraordinary means and extraordinary means usually translates as super. Like I said from Mortal Kombat: Deadly Alliance: Nitara, Drahmin, Hsu Hao, Frost, Jax, Kitana, Raiden, Reptile, and Cyrax are all unlockable characters -- Blaze and Mokap, on the other hand, are hidden characters. The real question we should be finding out is how do we get the HIDDEN characters...I think we all ready found out who the Super Unlockables were before the game even came out...
