It costs $15 to buy Blacklight from XBLA and its proven enough of a hit to get Zombie fired up on the sequel. There'll be no content updates coming to the original game only bug fixes CEO Mark Long informed.
Blacklight Tango Down 2 should release August 2011 say Zombie, and it will likely arrive for Xbox 360, PS3 and PC like the original. Did you help toward the sequel effort?
