SDK Info:Custom models are now supported and very much a reality now! And that includes survivors, special infected, common infected and weapons. Not only that, it seems the weapon functionality can also be edited. So what does this all mean? Well it means mappers can have custom survivors, special/common infected and entirely new weapons unique to just their campaigns (i.e map side modifications, NOT server side)! The L4D modding scene just got a little more interesting boys and girls.
Then there's also the news that the first L4D2 DLC pack will be bringing back Bill, Francis, Zoey & Lous in a meetup with the L4D2 guys.
