Alerts

Alerts are missions in DC Universe Online in which 4 players are joined together in a group and placed in an instance, the only exception being the very first alert players have access to, ALERT: Calling all Heroes!, which is a solo mission.

The group works together to complete a series of missions within the instance. Each Alert has several smaller bosses leading up to a main boss at the end. Players may access Hard Mode alerts once they reach Level 30. Hard Mode Alerts have a higher difficulty than Normal Mode Alerts and reward players with Marks. Alerts are accessed by queuing through the On Duty Menu.
