Players in the campaign mode take control of Lynch, who is backed up by Kane (except in the last mission, where the player takes control of Kane). The online enabled cooperative mode allows one player to take control of Kane. Players can carry two of any weapon they can grab from dead enemies, but unlike the previous game, cannot swap weapons between allies. Players can take cover through a button press. While still having regenerating health, players can also get knocked down, though are able to immediately get back up. During single player missions, allies are invulnerable and cannot be given commands, making it unnecessary to look out for them. Unlike Dead Men, the PC version does not support split-screen co-op.
Multiplayer
Fragile Alliance returns along with two new variant modes (Undercover Cop and Cops & Robbers). The returning mode still has a group of players attempting to grab as much money as possible while escaping police forces and possible traitors. Undercover Cop follows the same fashion while a randomly chosen player must prevent the team from escaping. Cops & Robbers has a group of player controlled police officers going against the criminals still planned to grab money and escape.
The end of each match will allow players to buy new weapons from their heist money.
There is also a single player variant called Arcade where players must accumulate as much money as possible for high scores while surviving increasingly difficult rounds.
