You are a mighty warlord who has landed upon the Unconquerable Islands, seeking to put that name to the test. To rise to this challenge, you must make strategic decisions, battle through hardened defense systems, and turn every castle, kingdom and PvP arena into a fresh conquest!

Once you've made a plan, your base will work night and day, gathering resources and sending troops to clash with the enemy fortress—even while you sleep. So strike up the drums and march your army to war in this idle military simulator!

If it's multiplayer competition you're looking for, Idle Siege also offers a PvP mode where you'll go head-to-head with other players in gladiator combat.
