Players can also partially communicate with others via the player model. The player's online ID display matches with that of their respective team.

Some games require the player to be on a team.

The player itself, like the protagonists, is represented with an arrow of the designed color. Like any ally/enemy in missions, they are labeled with a dot on the minimap, along with a name, where the player can identify another player throught the cursor and the screens in-game. Players are labeled with a certain color that represents their characters. GPS waypoints can still be placed on the radar and are visible to all players, along with the guided route (if enabled through the main options of the game). Weapons pickups now will have a larger amount of ammunition when picked up and are labeled differently ( Pistols from Shotguns), but aren't specifically defined (An assault rifle will be either the Assault Rifle (AK-47) or the Carbine (M4)). Health pickups now can be collected while in a vehicle, restoring player's health and vehicle's damage. Pickups are deployed across the map and are labeled with a specific icon. The player can always sprint and will never get tired, and can change weapons more quickly. Gameplay features differ slightly to that of standard single player. Despite this, un-patched installations of the game still have multiplayer enabled. The multiplayer, along with the online leaderboards, were removed from the PC 'Complete Edition' updated version of the game on March 19, 2020, due to end of support of Microsoft's Games for Windows Live platform.

The game requires a working internet connection or connected to a Local Area Network (exclusively for PC version) and supports up to 16 players (Xbox and PlayStation), and up to 32 (PC). Multiplayer in Grand Theft Auto IV is hosted on the PlayStation Network (PlayStation), Xbox Live (Xbox), and Games for Windows (PC).
