Teams are a form of player categorization, with each team yielding different perks and having unique objectives. Most teams are selected upon joining a server, and teams may be changed in-game by clicking "Teams" on their in-game Phone.
The five teams in Mad City are listed below:
|Team Icon||Team Name||Objective||Starting Items||Team Color||Spawn Location|
|Prisoner||Escape from Prison or participate in the various jobs.||Empty-handed||Orange||Prison|
|Police||Prevent Prisoners from escaping Prison and apprehend Criminals and Villains.||Pistol-S, Taser, and Handcuffs||Blue||Police Base and Easter Isle Police Station|
|Criminal||Rob Heists while avoiding being arrested.||Pistol||Red||Criminal Base and Warehouse Criminal Base|
|Hero||Kill Criminals and Villains with the aid of superpowers.||Empty-handed||Yellow||Hero Base|
|Villain||Rob Heists while avoiding being arrested with the aid of superpowers.||Pistol||Purple||Villain Lair|
- Main article: Police Base
Police can spawn in either the Police Base or Easter Isle Police Station. Both can be used to equip weapons, cash in heists, change clothes, and to view the bounty board, although neither are protected from enemy players as they are capable of entering them through various means.
- Main article: Criminal Base
Criminals respawn in either the Criminal Base or the Warehouse Criminal Base. Here, they (as well as Villains) are protected from players of enemy teams, can equip weapons, cash in heists, and change clothes.
- Main article: Villain Lair
Villains respawn in the Villain Lair. Here, they can equip Villain-exclusive powers and are protected from players of enemy teams.
- There are four other teams that are not playable through normal gameplay.
