Rotten Forest 1
"Summon your troops, General! The forces of darkness are relentless in their attacks against our beloved kingdom, and we must take action. Reports indicate that the area known as the Rotten Forest is indeed rotten; as a portal to the netherworld has opened in the midst of the woods.
The dead find no rest in this forest, and vegetation turns against any who wander into it. You must lead your forces into the Rotten Forest and get to the root of the problem!"

Rotten Forest is the fifteenth stage in Kingdom Rush. It requires the Premium Content in the Flash version.
