I mainly fight on expert but until I get to Shoa Kahn it becomes well...

I dare not venture into the land of expert. I can barely survive on hard. Sometimes I suck even on medium. Not until I boost my power levels over 9000 will I attempt expert.

Most of the time I play it on expert, I only play on medium when I want to get an arcade ending with a character I don't want to practice with.

Currently trying to beat the Ladder on Expert for the achievement, any tips? Shao is crazy hard.

:(

Jump over him until he makes an attack with long delay, then attack.

I use Scorpion and I have not yet beaten Shao Kahn yet, also Shang Stung is a dick on expert.

The bosses are the easiest thing on expert in tag ladder. Its 2 against 1.
I didn't finish tower yet so Im not sure if it ends up becoming goro+kintoro on the tag ladder. Khan is a little hard even with 2 characters.

Tag ladder on expert will make you pull your hair out. I learned ALOT by beating expert mode and I noticed that you must use your enhanced bar as soon as you get it each time or you will lose 100% to tag out characters.

Mileena and Sindel are crazy hard to beat and can do combos on you for over 70% as a tag team.

I haven't been playing the Arcade Ladder much but I did beat it on Expert once. Very tough. Shao Kahn and Shang Tsung were very hard, Goro was the easiest fight though.

The easiest way to beat Kahn on the latter is with scorpion. Just jump back and teleport in the air. keep doing this for the easy win
