Detention Centers are a type of mission which can occur in both Campaign modes and Endless modes. The primary objective of a Detention Center mission is to find the detention block and rescue either a detained agent or a high-value Prisoner. If the detainee is an agent, the reward for rescuing them is having that additional agent in your team; if the detainee is a Prisoner, the reward for rescuing him is credits.

If an agent has previously been lost in the field, then that agent will be the detainee in the next Detention Center mission. Otherwise there are equal chances of finding either a new agent or a Prisoner, unless there are already four agents in the player's team, in which case the detainee is always a Prisoner.
