Hmm. I would love to hear your strategies for this fight. Last night I went from medium difficulty to very hard and I got to the second endurance fight, but the Sub-Zero fight is so hard for me. I don't have probs with any of the other characters, but Sub-Zero gets me every single time. It's mainly because of his very fast recovery time from the ice shard. Even when standing real close to him, blocking and immediately launching a counter flying kick doesn't even work, he just blocks it in most cases. I tried standing in front of him and blasting fireballs all the time, but he can freeze you like that, you need to be pretty quick and keep up the rythm.
