Portcullis is a daemon which temporarily reduces the effectiveness of breaker programs. While Portcullis is active, programs break 2 fewer firewalls per use, down to a minimum of 1 firewall broken. Portcullis has a duration of 3–5 turns.
Portcullis 2.0 is an archdaemon which can occur from mission difficulty 5 and onwards in Endless modes. It has the same effect as Portcullis, but lasts for the whole mission instead of a shorter duration.
