The Containment Room is a location and boss in Mission 06: Resurrection in Devil May Cry 4. Contrary to its name, you don't actually fight the room itself: the goal is to break the thick, electrified glass window which separated Nero from Agnus. Eventually, while returning to Fortuna, Dante comes across this room and must battle several Gladii and Bianco Angelos.
The Containment Room contains launchers for Gladii, as well as poison-gas jets and an electricity-dispersing battery. In the lab behind the Containment Room, Agnus stores the Yamato, as well as several other pieces of scientific equipments.
At the beginning and during fight, Gladii will spawn from the sides of the room to attack you. Also, Agnus sometimes sends electricity through the ground to hurt you. There is a small hub in the middle of the room. If you stand on this, Agnus' electricity will miss you.
