A GREAT combo seems to be a damage heavy combo done between special tag teams. So far the easiest seems to be for Marshall Law/Paul for most people. The input for that is:
+ , quickly tap , then quickly tap and Paul will come rushing out very quickly with blue sparkles around him. With Paul press , and Law will automatically switch places with Paul with a yellow aura on his hands while the opponent is mid-air. You have to time it right, but press and it should zoom in on Law from his back punching your opponent followed by the announcer yelling out "GREAT!" plus your achievement poping up. NOTE:This can be done in Practice Mode.
Here is a video of this happening (Around 8 seconds):
first of all, this cheevo is not about making a ton of hits..
here's how i did it:
pick marshall law & paul & any opponent (maybe large characters are better). do law's poison arrow by pressing F2~1, during the stun animation quickly tag in paul & press 22. quickly tag in law & he is suppose to do a flip kick but this move should whiff... when it does quickly press 1. law should do the backfist & when it hits, the announcer will say great.
remember the flip kick animation will miss & just press 1 so law will do the backfist. if u have done this correctly, the cheevo should unlock
just substitute the numbers on my post to the xbox controllers buttons
law (Forward Y~X) then press tag button to call in paul, as paul, press YY then press tag button again to call in. law again, law should back flip & whiffs, after which just press X (backfist) when the backfits hits the opponent, the announcer will say "great"
why can't u guys use "RP (right punch). LP (Left Punch). RK (Right Kick). LK (Left Kick)when u guys write these guides? The reason is, some of us change our button config, so the instructions u give don't work becuz the buttons are different. Just a suggestion cuz I'm having a lil trouble doing these.
