PvZGW2 Crazy Ops SOLO (Easy Method)

The easiest method of completing ops by yourself on crazy difficulty in PvZGW2. I recommend using a splash-heavy character like Plasma Pea, Electro Pea or Petrified Cactus. For zombies, I'd recommend Electrician or Captain Cannon. Alternatively, just use Toxic Brainz. It's integral you use the roof as cover.
