Check back at 6pm this afternoon for CVG's hands-on impressions with GTA IV's multiplayer mode. In the mean time, here are the first details from magazine reports last month...
GTA IV's 15 (yes - fifteen) multiplayer modes have been revealed, in Spain's edition of PSM3 Magazine.
Online multiplayer is accessed through Niko's mobile in the single-player game, where you can join up to 15 other players for shootouts and customise your character, right down to his or her race, hair and clothing.
As well as the obligatory deathmatch and team deathmatch modes, GTA IV's awesome-sounding list of game modes includes a Race mode around Liberty City, four-player co-op fights against the police and the very obvious cops vs. crooks team game.
One mode, Hangman's Noose, is based on a mission from the single-player campaign which has you protecting Mafia man Kenny Petrovic with up to four team mates. Very quickly you're ambushed by SWAT teams and have to fight and protect your way across the city.
In comparison Mafia and Team Mafia are more simple fetch-quests, with each player being dished out the same co-ordinates and tasks around the city, and everyone dashing to finish it first.
Bomb Da Base and others are presumably the same as the identically-named modes in the PSP Grand Theft Autos. "Free Roam" is presumably a glorified chat room, which sounds like a decent addition to us.
Look for more of our own impressions soon. The full list of known game modes is:
Car Jack City
Bomb da Base
Bomb da Base II

Cops N Crooks
