Left 4 Dead (Xbox 360, PC) that juicy and delicious zombie flick of a game developed by Valve and its newly-acquired Turtle Rock Studios, has already suffered its own share of delays, and now the game has been pushed back once again into a Summer 2008 release date, according to Valve. Left 4 Dead was previously tagged for a Q1 2008 release date, prior to the announcement.

We know you're a bit upset with the sad news of a delay, and we can't help but feel the same as well. It's quite the neat zombie shooter that we're waiting for: co-op play, with lots and lots of zombies to plow through like you wouldn't believe. Yep, like in the videos here.

We'll keep you posted as always. More updates to come!
