The Expanded Mod for Age of Mythology (originally known as Improvement Mod, and at one point AoM++) is a major content and overhaul modification that was originally released in 2015 for Age of Mythology: The Titans, and an open beta release for Age of Mythology: Extended Edition in 2019.


Work on Improvement Mod was started on in December 2013, when XLightningStormL experienced issues with the AI from MasterFoozle's SPQR mod, and experimented with getting the AI to advance. Eventually within a couple of months, the Improvement Mod had a small issue of new technologies and units, mostly ported from Age of Empires. By January 2015, the first public release of Improvement Mod was released.

Eventually in mid-late 2015 for the release of v1.2b, Improvement Mod was renamed to Expanded Mod, due to the "lack of improvements, and the focus on too much expansion" as well as to separate it from the mod of the same name for Age of Empires III.

Steam-wise, Expanded Mod was originally ported and posted on Moddb in December 2015. However, it did not receive any updates or official release unto the Steam Workshop due to file size issues. However, development for a Steam version proper began in March 2017, with a Facebook post announcing that the Titans version was most likely going to be retired. In July 2019, the Expanded Mod finally released in an Open Beta state on the Steam Workshop for the Extended Edition, and is updated consistently bringing in new updates.

Much of Expanded Mod's content is inspired by the early development version of Age of Mythology (including much cut content features), Age of Empires, Age of Empires: Online and Age of Empires II.


Improvement mod adds a large variety of units, boasting an impressive 105+ new RM units, with another several dozen Scenario Editor units. Units range from: Phalanxes, Griffons, Generals, Varangian Guards, and Medjay Agema to name a few of some 105+ trainable units.
