Garden Crazy is an achievement in Plants vs. Zombies: Garden Warfare. To get it, the player must complete Garden Ops on crazy difficulty.
Strategies
The difficulty can be varied, due to the online multiplayer aspects of Garden Ops.
While a victory can be arranged by several different players, if this isn't do-able, things that must be taken into consideration are the amount of rounds in the game, the amount of players on both teams, the classes each player is playing as compared to your side, and the map in particular that is being played.
A good amount of skill, having a good class and cooperative team, and being able to effectively counter the other team's players is a must if a player wants to succeed.
