Overview
A simple guide to unlock the Two can Tango achievement.
How to earn the achievement
You need to play alone to get this achievement easily. You also need to be good with Melody or Bard.
Go in coop mode, and then choose Melody as your first player character. You need to use Melody or Bard since they’re the easiest character to play.
Go in All Zone Mode, and let the second player die, but control him so he’ll follow you, to make it easy. Once he died, play as if you were in One Player Mode, kill the miniboss, and then go to the second floor.
The second character will be ressurected, so let him die again, and continue etc.
Beat the Zone 4 boss, you’ll earn the achievement, even if the second player is dead.
