Inactive Devastators are fully functional Devastator walkers that have survived the initial outbreak and Alpha Company counterattack. They are destroyable, and targetable. Unfortunately, for most of Night of the Dead, they are mere set pieces. Only during the final battles of the Apollo Security Team Campaign can they be activated.
Prior to the battle with Athena in the Apollo Security Team Route B, Players can activate the Devastators. There are five total, four in right portion of the Airlock, and one in the left portion. They are all blue in color, and under the control of the player who activated them. If a player loses a Devastator, they can get another one provided there are still Inactive Devastators remaining.
