Play Area

The play area defines where players should place cards that are in play, discarded, or a part of their library.

Defender
The Defender has the most important play area because this player defines the network structure.

The game always begins with the Defender placing the Firewall card in the upper left-hand corner of the Defender's play area. New network segments can be added down from the Firewall, and new devices added to the right of the Firewall.

Attacker
The Attacker has a less rigorously defined play area. Exploit cards should be placed in front of the Attacker's library and hand where they are easily seen by the Defender.
