All of Classic Smokes combos use no meter.
Classic Smoke only has 2 special moves, the spear and the teleport. His teleport is more like scorpions then regular Smoke. He does not have any of regular smokes special moves what so ever, no smoke bombs, no invisibility, no shake and no smoke steps. Ontop of that he also has no X-ray, no breaker and no enhanced moves. Thats not to say though he isnt a beast!
Classic Smoke does however share all of regular Smokes pokes and strings.
To Play as classic Smoke, you need to have a XBOX 360 that has been Jtagged with the MK trainer installed.
