Mirror Towers are available to the Atlantean Titans Kronos and Oranos through Helios, Titan of the Sun. The towers use mirrors to focus sunlight into a burning beam that is especially strong against ships.

Archimedes of Syracuse is credited in legend with the invention of large, hexagonal mirrors mounted in towers to burn invading Roman ships to ash. There is some evidence that these towers were copied from similar towers that defended the harbors of Atlantis. Atlantean mirror towers used highly polished orichalkos mirrors which could focus beams much further and hotter than the mirrors of Syracuse.
