Indie development studio Hidden Path have come a long way since first releasing Defense Grid: The Awakening back in 2008. Since then, the Washington based developer has helped Valve maintain Counter-Strike: Source and were a huge part of the Portal 2 ARG earlier this year. They’re also working side by side with Valve on the upcoming Counter Strike game, Global Offensive.
This close partnership is now making its way into Hidden Path’s Defense Grid by way of a Portal themed expansion pack entitled “You Monster.” Players will find eight new maps that follow a new story line, thirty five new challenge maps, and GLaDOS as a second narrator.
The expansion will launch on December 7th for $5.
