These maps maintain the high standard that Ryoko set for himself with his other successful mappacks. But what's more impressive is the fact that these maps all act as a cohesive set and have their own signature feel, different from Paradise Lost or Red Spectrum. And the Power Drive maps fit right in, as well.
My favorites are Gustav Garden, Rocket Rider and Das Jerk. Hollow Void is the standout dueling map here. Good job!
