Grab 15 Life icons (1up)
For now, the only life icon known is the one at the end of stage 3. To have him appear, you have 3 steps to fill:
1- Destroy the six parts of stage 3 mid-boss (3 left side, 3 right side)
2- Between the stage 3 mid-boss and the end of the stage, don't use your guard barrier (or auto-barrier when you're taking a hit).
3- At the end of the stage, when you see the energy power-up, go to the left. You will see some cones, shot the left one in Zetsushikai (Holding B). If done correctly, you will see the 1up. Repeat the three steps 15 times (you can go game over right after grabing it).
If you're aiming to the 1CC in Xbox 360/Arcade mode, this will probably come normally as the 1up is important if you want to have a chance.
