Somewhat later than I hoped, blame my motivation (lack of) for that. Hope you like it.
I’ll start releasing my next major series, Braneworlds, as soon as I can, I’m just waiting for one last model.
Just a note you might find interesting, I’m discussing with one of my friends who is a mapper about the posibility of making a Mod based on this idea. Likely it’ll be made in Left 4 Dead, but its just an idea for now.
