A bit about shipping lanes.
It's crucial to defend the Shipping Lanes! Begin with Warehouse Way, as you battle for the first time against the Syrup Devils, who can slow down your Ninjas by covering them in the evil goop! You'll also be able to build Infirmaries, which help your ninjas return to battle twice as quickly. You'll need to use cannons to repel Mr. Demon's minions on Industrial Boulevard. The Ol' Rail Road requires some new strategies as you deploy your ninjas and use cannons to deal with enemies. The final battle of this area takes place at the Shipping Canals, where the Ninjas have to fend off invading devils – on pirate ships!
