GSC Game World announced S.T.A.L.K.E.R 2 today, which they are touting as the franchise's next chapter. It will feature a "completely new multi-platform technology" developed by GSC.
"After the official sales of the series exceeded 4 million copies worldwide, we had no doubts left to start creating a new big game in the STALKER universe," said CEO Sergiy Grygorovych. "This will be the next chapter of the mega-popular game players expect from us.
The most recent S.T.A.L.K.E.R. title is Call of Pripyat, which was released in February. While Clear Sky was a prequel, Call of Pripyat picked up where the first game left off.
S.T.A.L.K.E.R 2 is scheduled to be released in 2012.
