 "Nothing travels faster than the speed of light with the possible exception of bad news, which obeys its own special laws."
– Douglas Adams

Laser is a new technology in the Beyond the Sword expansion pack.


Laser allows the construction of the Mobile SAM, the ultimate land-based anti-air unit; the Mobile Artillery, the most powerful siege weapon in the game; and the SDI.

Civilopedia entry[]

The laser, short for "Light Amplification by Stimulated Emission of Radiation," is a focused beam of photons, light energy released by excited atoms. Lasers rely on a phenomenon that occurs when a collection of atoms of certain elements are excited to the same state: they all release the same color of photon. When properly focused through reflective mediums, the result is a high-density beam of photons with innumerable uses, from military targeting to earthquake prevention.
