Before its time? Valve explains Left 4 Dead sequel to Ars is a sit down between Chet Faliszek and Ars Technica as Valve looks to assuage the anger of fans over plans to release a sequel so soon after the original Left 4 Dead. The gist of their reasoning is how much bigger a project this is than their Team Fortress updates, though he also describes how Gabe Newell had to be talked into the sequel, saying it was against the character of the company. Chet outlines all the content the sequel will offer, and provides reassurances that existing L4D mods will work with L4D2.
