GTA 4 Multiplayer

Team Deathmatch

• 2-8 Teams

Players work as a team to rub out the other teams for money, and the crew with the most cash at the end of the round wins. Take the other crew down. Remember to loot the cash dropped by deceased players. That's the way to get ahead!

Team Mafiya Work

• 2-8 Teams

You're a member of a crew doing contract work for the mafiya, including such plum gigs as escorting wanted men, picking up MacGuffins, and stealing cars. Work as a team to complete contracts before the time period ends and get the rewards. You'll probably want to do your best to scupper the other crew's work as well. Each contract you complete gives your team cash, and the crew with the most cash at the end of the round wins.

Team Car Jack City

• 2-8 Teams

Cars spawn parked around the map and the teams must steal them and take them to a drop-off point. The cash teams get for dropping off stolen vehciles depends on their condition - teams get less cash the more damaged they are. The exception to this are special bonus cars, stuffed with drugs, which give a set amount of cash on delivery no matter how damaged they are. Your crew has to get hold of whatever vehicles the boss wants. Whichever crew makes the most money wins.

Cops n' Crooks

• 2 Teams Only

A team-based mode in which the Crooks must get their Boss to safety, while the Cops have to take him down. The Boss is marked with a crosshair. This mode has two sub-modes: All for One and One for All, both of which can be won by the Cops if they manage to destroy the getaway vehicle.

All for One

One team is made up of Crooks and a Boss, and the other team is made up of Cops. The Cops are trying to hunt down and kill the Boss while the Crooks are trying to protect him. The Cops win by killing the Boss and the Crooks win by getting the Boss safely to the getaway vehicle and escaping.

One for All

Similar to All for One except there is no Boss. Here, the Cops win by killing all of the Crooks and the Crooks win by filling up a getaway vehicle with members of their team. Only 4 people can escape in the getaway vehicle. Players cannot respawn in this mode.

Turf War

• 2 Teams Only

A timed capture-the-base mode. There are a number of bases around the map that you have to take by standing on them for a short period of time. The more players that are on a base, the faster it can be captured. The more bases that your team owns, the faster your team's cash score increases. If the rival gang is on or near a base, you won't be able to take control of it, so do what you can to try to displace them. The team with the most cash at the end of the round wins.
