Stonehenge

Stonehenge is a difficult area with a twist: on the top and bottom lanes, any plants placed will have their damage and firing speed greatly increased! Unfortunately, however, on those lanes, there are way more zombies and stronger zombies, and sun gathering plants will not be affected by the strengthening.
