Altirus (Garry's Mod)

Altirus was a setting used by a small group of Garry's Mod players in which to base pseudo-historical (intended to emulate a real-world historical time-period, without following real or speculative alternate history) builds and lore. It was similar to the current form of the Altirus setting, but was left intentionally vague in many respects, and was the result of some collaboration between contributing players. It also posited that the continent of Altirus was largely isolated from the rest of the world until the development of powered flight, as established in earlier incarnations of the setting.

It was predominantly used by the aforementioned group of players to contextualize designs made with, and fights conducted with, the Armored Combat Framework (ACF) addon.

An entry for the setting and the player-made factions and equipment exists son the Armored Combat Framework wiki.
