03: Blundercliff

This is the last of the tutorial stages and will give you a new hero and tower. The enemies will be coming in from two different directions. Place at least one more Shock tower along the other path and place some pulse cannons in the middle area as well. You can leave the Assault unit in the middle so you can get as much coverage as possible with his AoE attack. Lay down your gatling and other towers as you see fit and upgrade them as soon as you have the money to spare.
