Battle Isle is a series of turn-based strategy/tactics video games developed in the 1990s by Blue Byte and released for Amiga and MS-DOS and later for Microsoft Windows.

The Battle Isle storyline is set on a fictional planet called Chromos, whose society is technologically slightly more advanced than that of contemporary Earth, possessing the knowledge of advanced robotics (robots), computers (AIs) and limited spaceflight (enough to set up space colonies on the moon of Chromos).

Players have various tasks, ranging from eliminating all opponent forces to capturing specific buildings or protecting certain units or places.

In some missions events from outside the battlefield can suddenly change the situation, giving players new objectives, reinforcements, allies or enemies.

Battle Isle 2 gave the player the entire screen, and merged move and attack phases, and introduced the 3-D display of combat.

Battle Isle: The Andosian War was entirely set in the 3-D environment and combined elements of real-time and turn-based strategies.

After a player survives the first few turns and the AI's overwhelming numbers using protected artillery and terrain advantage, the computer is usually unable to mount a proper defense.

Of those among the most notable is Blue Byte's own History Line: 1914-1918 from 1993, which moves the science fictionish climate of Battle Isle into the times of First World War.

In July 1997, an entry in the Battle Isle franchise was in the works by Blue Byte for the Panasonic M2, but it never happened due to the cancellation of the system.

In 2013, Stratotainment, LLC, a mobile game company owned by Thomas Hertzler (co-founder of Blue Byte), announced the development and the reboot of Battle Isle.
