In the demo, I remember the 1st...special attack one got was some kind of charged Buster Shot a la Megaman (though it sounded like Samus' charged shot in SSBB).

Let me tell you, that was the only useful special attack. Ranged, lots of damage, invulnerability while charging it, knocks enemies backwards a bit.

The other ones were almost useless. The 2nd one didn't have enough range to 1-hit-kill and put you at risk easily, while the 3rd one didn't deal shit of damage at all.

I don't know what special attacks there are there, but if there are only these 3, always use the Buster Shot. It's the only one that is actually useful.
