Erebus introduces Team Mode in The Breach game for 2–6 players, in which each player has to cooperate with other members of their team and counter their opponents.

Many ex-Breachers have betrayed the cause and their companions, and now control the Agents in the database. This new generation of sentient enemies will give the Breachers a real run for their money, and they will have to unite against these common enemies.

This expansion introduces Team Mode in which players, divided into Breacher Team and Corp. Team, must coordinate within the Erebus Database to lead their team to victory.

Each player on the Breacher Team controls an Avatar in the Database, while each player on the Corp. Team controls an Agent and Firewall I.C.E.s.

In Team Mode, the game ends when one of the two Teams wins the game.

To win the game, the Breacher Team must complete all the Objective Cards they have.

To win the game, the Corp. Team must complete all Corp. Objective Cards and the I.C.E. Cube on the Corp. Track must have reached or passed the Debug icon.
