How to unlock the Perfectionist achievement in EA SPORTS MMA - Definitive Guide
While this may sound difficult, keep in mind two things:
1) You can unlock this achievement on any difficulty. The difficulty can be changed from the Settings menu in your phone at any time during your career.
2) You can just shut off your Xbox/Dashboard if you lose a fight. However, if you do this, you will start at the beginning of that training camp i.e. with 8 weeks till fight. To avoid some tedious training, just exit Career mode before any fight that you think will be tough (Typically once you hit 15-0 or so). Then, if you Dashboard after a loss, your progress will be saved up to that fight.
Note: This achievement is missable. Also, this game auto saves after every fight. If you lose, quickly turn off your console. When you load the game back up, you should be back at the start of the fight you just left. Do this if you ever lose to make sure you get the 20 consecutive wins.
After you win your first 17 fights, you should have the Mystic Championship or the Strikeforce Championship. After that you will have to defend your title for three consecutive matches, after you have won those last three the achievement will pop.
The first 17 matches should not be hard at all but I had some trouble with the last three. Your opponent will guard his face so you need to keep the pressure on and attack when you find an opening. If your opponent is hitting you hard or constantly getting easy hits on you just move away and let yourself regain stamina. Your stamina is important for staying strong during the fight.
