Security Hall is a level in Sonic Adventure 2. This is Rouge's third stage and the eighth stage in Dark story line. The player must try to collect three Chaos Emeralds in five minutes. The background music for this level is "I'm a Spy", with Tabitha Fair as the vocalist.


In order to steal more Chaos Emeralds for the Eclipse Cannon, Dr. Eggman suggests a three part plan. First he will distract the military guards of Prison Island. Then Shadow will place a bomb among G.U.N.'s weaponry that will explode in fifteen minutes. Rouge infiltrates the G.U.N. base and has five minutes to steal the three Chaos Emeralds G.U.N. has acquired and meet up with Shadow and Eggman before the bomb goes off.

Stage layout

Rouge begins the level by defeating an enemy. She then moves on to explore the Hall and look for the emeralds. In this stage there are giant fans, springs, locks, and enemies as obstacle. Rouge must collect the three Chaos Emeralds hidden throughout the level in five minutes.

The stage has three different floors which contains Safes that can be dug into. The floors are divided into three colors: red, blue, and yellow. They are also divided into three different blocks, or sections. At the start of the level a random color floor is already active. The safes can only be entered once the switch for it has been pressed. Switches to these are located in the upstairs room. Only one switch can be active at a time.

Floor Color Block A Block B Block C
Red 3 2 1
Yellow 1 4 2
Blue 1 2 2

Level Up Item

The Treasure Scope can be found in a room that is protected by steel boxes. Mystic Melody is required to obtain it.


Collect 100 Rings

Mystic Melody is required for this mission to collect some rings that are hidden by the Ancient Shrine. Some Rings are hidden inside containers, and others are inside safes.

Find the Chaos Emeralds within 3 minutes and 30 seconds

Security Hall is not very large, so finding the emeralds with the radar should not take too long. Begin by gliding around the lower floor, and if nothing comes up, move to the top. Note that Chaos Emeralds can be hidden inside safes.

Find the lost Chao

Take the pulley to the top floor and stand in the highest floor in front of the yellow letters at it's beginning. Turn on the Treasure Scope and the player should see a spring on top of the letter "B". Bounce from it to reach a platform where the player finds the lost Chao.

Complete Hard Mode

The first Chaos Emerald is hovering above the fans to the right of where the player begins. The current juggles the player above the Emerald's location, so the player has to perform a drill attack to grab it. For the second one, head to the top floor and navigate through the lasers and toward the yellow safe switch. Climb up one of the two large boxes just in front of it, and glide over to the Emerald floating between them.

The third Chaos Emerald is inside the safe directly below the crusher, on red floor, B block. First open the red safes in the Switch room, then go to the B block and climb to the steel platform. Use the Treasure Scope and hit the Spring, which will make Rouge activate a switch that will stop the crusher.

Big the Cat cameo

At the beginning, jump over the right rail and float above the fans at the upper left corner, closer to the bar wall. Big is seen under the floor, holding onto the wall below. Careful Drill Driving under the floor, followed by a glide toward the central pillar, will allow a better look, although actually descending as far down the wall as Big is, will result in death. In Hard Mode, Big appears clutching on the money fan on front of it instead.

Chao Containers locations

  • Red floor, A block: On the ground and in the middle of the two farthest metal crates, opposite the safe rows.
  • Blue floor, boundary between B and C block: Inside the safe directly above the metal crate.
  • Switch room, yellow area: Next to the crusher and between the two metal crates.


  • For mission 2, if the player goes up to the very top area, he/she will find a shrine that activates when playing the Mystic Melody. This will give a lot of rings laying around in the spot which can help with this mission.
  • This is another mission 3 level in which the Mystic Melody is not required to get the Chao (the Treasure Scope is needed which requires the Mystic Melody though). This can be finished very quickly.
  • If you look closely at the money floating in the air Sonic's face is on it.
