Pretty self explanatory but thought I would give a brief guide.
This stage is based on Aerial combos Solo. Stages 1 & 2 you will have no issues with. The boss stage can be a pain. There are 3 opponents and the first is the problem, yellow bob power ranger. When the level starts RUN!!! at him, he will immediately throw items or shoot you with his ray gun to knock you back. When you hit the ground, roll towards him to reduce distance. Once you have him in the air rinse
and don't let him up. Once you defeat him the level gets much easier.
Opponent 2 is a bear with low gravity (easy long combo), knock in the air with
timing it right you can do this in 1 or 2 combos.
Opponent 3 is last and another bear with increased stage speed (your opponent will fall fast but your movement speed is increased). Again knock in air with
, now you can use
to get a long combo for money point which will help with;
(I also found this was the best level to rinse and repeat for the Super Combot DX Complete achievement, as its not that difficult and no real demand)
But you can rinse
to KO quickly. Once this opponent is defeated the achievement will unlock after some dialogue.
