Well it came at last, the new map by Daniel "Invine" Deen, who continued the great work of Bo "Kleineman" Kleinhesselink in the map called mp_dahman. Invine was made famous by making the mp_smalltown, which unfortunately wasn't recognized as a competitive map. The map itself isn't finished yet, but with the help of Vita Nova the beta version is scheduled for 30th of May.

Is this the thing CoD4 needs?
