Added in the GTA Online: Further Adventures in Finance and Felony Update
Trading Places
In Trading Places, players are battling in variable teams. When a lower-class trader player (Loser) kills a member of the opposing team, he is switched onto that team, becoming the VIP (Winner). The player killed is switched from the winners to the losers.
Power Play
Power Play is similar to a deathmatch, except that it has numerous power-ups available. Start, end, and pickups are announced by a cybernetic voice.

Entourage
In Entourage, one player is the Target, the rest team are bodyguards, and an opposing team are the Assassins. The Target must get to the extraction point before the time limit without being killed. The bodyguards' objective is to protect the Target from Assassins. The Assassins must kill the Target or prevent the Target from reaching the extraction point in the time limit. Assassins have unlimited lives but weaker weapons. Bodyguards have stronger weapons, but 3 lives before they are eliminated from the round.
Added in the Bikers Update
Slipstream
In Slipstream, Players work in teams of 2 or more to hit checkpoints at the same time. Teams need to take full advantage of the other players' slipstreams for speed boosts – and using well timed attacks to melee opponents off their bikes – to finish first. All players use equivalent bikes.
Lost vs. Damned
In Lost vs. Damned, players are split into two teams, Angels and Devils. Every 60 seconds, each team has a phase in which they score points with stronger weapons (Angels during the day, Devils during the night). The opposing team with only a melee weapon has to hide, but can get kills to reduce points during their off-phase. The name is an obvious reference to
Grand Theft Auto IV: The Lost and Damned.
Deadline
In Deadline, Up to four players are set in differently colored
Shotaros over a large floating platform which makes up the arena. The objective of the game is to take out the rival players by using the bike's energy trail to block their paths. Any unfortunate player that touches the rival bike's trail will instantly explode, losing one of their lives (which number varies on the lobby setting).
Kill Quota
In Kill Quota 16 players in teams of 2, 3, or 4, go against each other using 4 loadouts of 6 weapons. Starting with a powerful weapon, such as the RPG, and ending with a one kill melee weapon, such as the Knuckle Dusters. The first team to run through all weapons in the loadout wins.
