Just had an email from Rockstar letting us know the official LCS website has been updated. There's loads more information on there now and new screenshots, downloads and audio.
And the long awaited second trailer is now online. Make sure you watch that.
There's also a page on the new multiplayer game modes we found out about earlier. Get Stretch and Liberty City Survivor are there, along with one we haven't heard about so far called Protection Racket. It seems that teams will be swapping between attacking and defending roles each round. Once the attackers have reached the defenders base, they must destroy the four limo's parked inside, after accomplishing that, the roles reverse and a new round begins.
There are 13 new screenshots on the site which I have added to our Gallery.
Two new teaser sites have also been launched, they are Bathtub Gin Still which we already knew about and Electron Zone Radio.
