Rockstar denied the fact there would be a multiplayer mode, however new details have emerged on a two-player co-operative mode. Small gaming site SPOnG got a chance to see a preview of the game in action and it was inevitable they were going to ask about a multiplayer mode. The response they got was pleasently suprising

There will, however, be a dedicated co-operative mode for two players. During the game, a scene ensues when the player rescues a girl from a burning building. After this act of gallantry, she becomes your in-game girlfriend and also, a playable second character. Most of the co-op action takes place inside vehicles, with player one driving and player 2 shooting. When the co-op mode is opened, icons will display the missions available to two player on the game's map.

What's more, a plethora of two-player minigames will be included in San Andreas. Unfortunately SPOnG has no specific details regarding these right now, though we can confirm that various parlour games will be included.

So this is going to mean a whole new adventure for gamers when playing San Andreas. Rockstar sure have taken this game to a whole new level, in fact, more than that, it's on a level of it's own. No game will ever surpass the immense playability of GTA:SA.
