Ancient Warfare 3 is an action, simulation, and strategy sandbox centered on making battles your own. Players can set up custom scenarios in a battle editor, arranging units, objects, and traps, choosing an environment and equipment, and adjusting rules. They can then fight the encounter or watch it unfold. That combination makes the game as much about designing a situation as taking part in one.
Its play spans familiar and speculative eras, from the Stone Age and medieval periods through the world wars and modern settings to futuristic science fiction. Deathmatch, conquest, king of the hill, and zombie survival are among the available modes. A broad selection of units, objects, and equipment supports varied setups, while Steam Workshop lets players share creations and draw on community-made battles, campaigns, and other content.
The editors extend beyond battlefield layouts: players can make custom units and equipment, import models for items and objects, and use a visual scripting system to define behavior and rules. The result is a flexible format where a session might involve a designed objective, an improvised skirmish, or simply spectating a constructed battle.
