Rockstar has just released more information about the multiplayer modes that gamers can expect to see in Grand Theft Auto IV. You can find out the full list of game modes and details after the jump.

• Team Deathmatch - Teams duking it out in Liberty City
• Team Mafiya Work - This mode has players taking contracts from the mob. The contracts will have you do everything from bombing targets to taking someone out.
• Team Car Jack City - Teams must steal cars that randomly spawn around Liberty City. These cars must then be taken to drop off points in the city and you are given cash in exchange. However, some cars contain drugs and are worth extra cash.
• Cops N' Crooks - 2 Modes "All for One" or "One for All" - All for One has players on the Crooks team guard a boss that they must take to an extraction point. The Cops team must take out this individual to win the game.  One for All has players rush to a getaway vehicle that they must pack with 4 croos, but there is no boss. The Cops win this mode by killing all of the Crooks.
• Turf War - This is your standard control point style play. In this mode players must capture various points on the map and maintain control of them.
