Cobra Kai The Karate Kid Saga Continues Cheats & Tips

To get the Frienemies achievement/trophy you have to finish Demetri with Hawk or vice-versa. Depending on which dogo you decide to play as, either Hawk (Cobra Kai) or Demetri (Miyagi-Do) will be your opponent when you reach the end of the Shopping Mall level. All you need to do is keep attacking him with any character or attack until his health is almost gone and then switch to Hawk/Demetri to deliver the final blow.
When you unlock the Frienemies achievement/trophy you will also fulfill one of the Challenges towards the Brown Belt achievement/trophy.

To get the Cruzader achievement/trophy you must beat Cruz with a Special Punch. Your starting characters begin with the Dojo Punch Skill unlocked (LT + X on your Xbox controller) and they may also have the Personal Punch Skill (RT + X on your Xbox controller). Use either of these two punch attacks as the final blow to defeat Cruz, the final boss of the Mini Gold and Arcade level. When you unlock the Cruzador achievment/trophy you will also fulfill one of the Challenges towards the Purple Belt achievement/trophy.

To get the Dodge the Irony achievement/trophy you must defeat Armand with Miguel's Personal Jump Skill. Miguel is not an available character during the Miyagi-Do campaign so this can only be done during a Cobra Kai playthrough where you will encounter Armand as the final boss at the end of the 5th Avenue Bar Stage.

All you need to do is keep attacking him with any character or attack and make the final blow Miguel's Personal Jump Skill (hold RT + press A on your Xbox controller). If you have upgraded Miguel's Personal Jump Skill the added damage over time (DoT) effect from the attack will also count. When you unlock the Dodge the Irony achievement/trophy you will also fulfill one of the Challenges towards the Purple Belt achievement/trophy.

To get the Randomizer achievement/trophy you must make all Tournament brackets nameplates fall off the panel. This is done at the end of the tournament stage when the tournament bracket glows green.

The tournament bracket is an environmental item which you have to lure enemies near to and then throw (RB on your Xbox controller) them into the board. Once you have performed this feat four times along the board the Randomizer achievement/trophy will become unlocked.

It is important to remember that you must knock all the nameplates down before you kill all the enemies and progress as the achievement/trophy will not unlock if you don't get the 'Go' arrow before moving forward.
