Free Mode
As much as we've loved Cops 'n' Crooks, Free Mode is going to be the bread and butter of GTA IV multiplayer. Here's the deal: Up to 16 players can run around Liberty City doing whatever they want. Create your own game modes, hunt for Easter eggs, work together to survive a six-star wanted level -- if you can dream it, there's probably a way to do it. And this mode begins in the most unusual, jarring way.

You begin in a standoff with the other players. Everyone spawns in a circle and there is, at least the first time you play Free Mode, a brief moment of surprise when no one does a damn thing. This lasts a few seconds before someone takes out a gun and shoots their neighbor in the face. But this standoff isn't just to start the killing (and jump people around the city with their first respawn); it also allows players to talk about what they want to do in Free Mode. This way you don't have to hunt for anyone in order to discuss plans to take a bus caravan down to Star Junction or to agree that there will be a knife fight atop the Algonquin Bridge. Or you can just blow each other up. It's Free Mode -- do whatever the hell you want.

As with the other MP modes, the host has plenty of options to customize the experience, from setting the level of traffic, to turning cops on or off, to the time of day, to weapons available and so much more. This also includes setting a time limit if you don't want Free Mode to last forever.
Team Mafiya Work
Your cell phone plays a major role in the single-player campaign, but is a fairly minor thing inmultiplayer. That is, until you play Team Mafiya Work. Throughout the match, you and the competing teams receive text messages assigning you missions from the mafiya. This might mean jacking a specific car, assassinating an informant, or any number of other errands. The team that completes the objective first scores the cash. Just don't get cocky. As soon as one errand is completed, another one pops up on your phone.

While most team-based games play best with just two groups, Mafiya Work is better with more teams. The errands given are usually fairly easy to pull off and something that a small group of three or four people can handle. You get greater chaos and a more competitive match with more teams vying for the same objective.

Team Car Jack City
Taking the name Grand Theft Auto to heart, Car Jack City has teams stealing selected cars from around Liberty City. The marked cars show up on your radar as do dropoff points. Of course, you're in competition with the other teams, which makes things interesting. Unless the car is secretly stuffed full of drugs, it loses value as it takes damage. So when you get in a car, the other teams will target you -- either to jack the car from you or destroy it outright.

Turf War
Turf War is your classic capture-the-point mode. There are three points on the map (though there may be options to add more) and just two teams to try and hold them. To snag a point, you need to stand in the circle at the center of the base. The more people who stand in the circle, the quicker the base is captured. Don't worry, the points are in the same neighborhood -- you won't have to run around all of Liberty City. You could wander off it you wanted to, but that's not really the point of Turf War.

Cops n Crooks
There are two teams one cops and other crooks. The crooks have to escort their boss to a section safely while the cops have to kill the crooks boss before they reach their destination.
