Erebus servers are the silicon heart of the Corporation’s mysterious knowledge, where it all began. Nobody knows the physical location of the servers, which is why its impossible to have direct access to them.

This area is well protected by Agents. The Agents are not just a clever AI, anti-tracking software will not be enough they are managed directly by incredibly smart Breachers, who have been seduced by the power and richness that the A Corp can grant them. If you see one Agent, dont waste time, a single second can make a huge difference. Immediately hide yourself, run misdirection routines, and activate cloning systems. Don’t let them see you!

The Breach Erebus expansion lets you play in Team Mode! One group of players will carry out the Breachers raid mission, and another group of players will play the role of the Agents!

The task of the Agents is to block the information, making it more difficult for the Breachers to recover while waiting for the End Game activation. A special Guardian Track will reveal a Mission Card to the Agents, telling them how to win the fight.

Erebus introduces Team Mode in The Breach game for 26 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.
