Anti Air

The Anti Air was a trap in Dungeon Keeper that fired chicken guided missiles. It was concealed before activated, and was effective against all air units, including Tiny, Dragon Whelps, Ghosts and Fairies (during survival raids).
Keepers required a level 7 Workshop to access this trap.
==Notes==
*Hidden until revealed by nearby enemies, Dragon Breath, or by the scouting boost.
*Revealed anti air traps were a primary target for Trolls, which would travel great distances to destroy them.
*If you placed one behind a door next to a resource room, enemies that had Scout would have it revealed, meaning their Trolls could take down the door to get the trap, which also gave easy access to their Bile Demons and Skeletons.
*Was most effective during defence raids such as survival raids, as they would often have air units.
*Had very long upgrade times and provided small quantities of DCR compared to other traps.
