From the description:

For four consecutive weeks starting on June 2nd, a new pair of maps will be released each week providing new environments and strategic experiences, requiring new ways of thinking to beat back the aliens and protect the cores.

Today’s Map Pack 1 release includes two new challenging environments – Service Interruption and Height of Confusion. An obstructed road to the core housing gives the aliens a significant advantage in Service Interruption. Choose your towers wisely! Height of Confusion has a wide open surface, making for endless possibilities! Build anywhere you want in your defense of the power cores!
