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!, and its villain counterpart, ALERT: Villains Wanted!, which are solo missions.

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.

Access
In order to enter a alert, players must queue up using the On Duty Menu (Default PC Key 'Y'). They will then be placed in a queue that searches for other players who wish to do the same alert, and be prompted to enter the instance.

Players must reach a certain level to gain access to a certain alert and additional Combat Rating or DLC requirements must be met.
 * Tier 1 hard alerts are available to at level 30.
 * Tier 2 hard alerts require a Combat Rating of 43 to enter.
 * Tier 3 hard alerts require a Combat Rating of 53 to enter.
 * Tier 4 hard alerts require a Combat Rating of 70 to enter.
 * Tier 5 hard alerts require a Combat Rating of 84 to enter.
