Mortal Kombat Story Mode Walkthrough Part 2: Johnny Cage. This includes all cutscenes. This includes how to beat the first fighter, Sub-Zero, and the second fighter Raiden.

Tips: Beating Sub-Zero: Sub-Zero doesn't fight to his fullest potential here, but he will bust out a few of his freezing tricks now and then. He prefers, strangely, to do his slide, especially when you're airborne. Stay on the move and use Sonya's kicks, and use her Energy Ring Blast to shatter any of Sub-Zero's clones if he makes them.
Fight #2 (Raiden): Raiden wants to get up close and personal with Sonya, and who can blame him? Sonya's Arc Kick and plain uppercuts work well here, but if you create too much distance, Raiden will use his long-range attacks to try to even the odds. Stay on the ground as much as possible, but don't be afraid of setting up a jump-in if Raiden is on his back.
