Boss Battle Boss

Boss Battle Boss is an Achievements (PvZ: GW2) that was added in the Trials of Gnomus DLC. To earn it, the player must enter the Mystery Portal inside the Town Hall and defeat a boss in Boss Hunt on Craaazy difficulty.

Trivia
* This is comparable to both the Garden Crazy Achievements (PvZ: GW) in Plants vs. Zombies: Garden Warfare and the Insanity achievement in Plants vs. Zombies: Garden Warfare 2, as they need the player to complete a mode on Craaazy difficulty.
