Capcom Fighting Collection

This is actually a pretty easy Achievement once you know how to get it done.

Change your game to use the following settings :

Game Difficulty : 0
Resistance : 1(Minimum)
Timer Speed : 1(Minimum)
Max Rounds : 1

Start the game with 2 controllers if possible or you will also be able to do this to your CPU Opponent easily.

Choose any Pilot and then when choosing your BOT Choose : FORDY Category and KILLER BEE as your chosen Bot.
Make sure when choosing your opponent to choose :BLODIA Category and BLODIA as your opponent Bot.

When the match starts hold down to charge your Super(Power Gauge). Once your gauge is full move your character right next to your opponent and do your special move
This performs an 18 hit combo and will unlock the Achievement. The opponent is important as when doing the special move on other characters I noticed 17 hits which is not enough for the Achievement.
