Overview

The green glass protecting a defense unit in The ARK, from Shadow the Hedgehog.
In Shadow the Hedgehog, defense units appear in The ARK and Space Gadget. When completing the Dark missions of these stages, the player must destroy the defense units in order to let the Black Arms take over the Space Colony ARK. To achieve this, the player must destroy them using firearms, though they will be protected by glass barriers that can block a limited number of the player's attacks. They also have Ark Missile Turrets that attack intruders. The player has to destroy six defense units in Space Gadget, and four in The ARK.
