Olympus: Idle Tower Defense

Mount Olympus is under siege, and only the gods can hold it. Olympus Siege is an idle tower defense game set in Greek mythology: invoke the twelve Olympians, unleash their blessings and hold your throne against endless waves of mythic monsters. Your defense keeps fighting even while you are offline.

TWELVE GODS, TWELVE BLESSINGS
Awaken Zeus, Poseidon, Ares, Apollo, Athena, Aphrodite and the rest of the pantheon. Every god grants a blessing that changes how you defend: Chain Lightning arcs through the horde, Tidal Waves sweep the field, Whirling Death spins blades around your throne, Sun Strike calls down pillars of fire. Mix them into a tower defense strategy that is yours alone.

AN IDLE TOWER DEFENSE THAT NEVER STOPS
Waves of shades, harpies, cyclopes and hydras climb toward your throne, and every tenth wave a boss breaks through. Hold the line, push deeper, and when you close the game the siege goes on: return to souls, ichor and reliquaries earned while you were away. Idle progress, offline rewards, and no need to watch the screen.

CHAMPIONS OF THE DEEP WAVES
Hold long enough and elite champions join the horde. The Stormrunner sends nearby enemies racing, the Bronzehide shrugs off your weapons and the Godwarden wards the horde against your blessings. Every champion you fell pays a rich reward.

UPGRADE YOUR DEFENSE IN THE PANTHEON
Spend souls on hundreds of upgrade levels: damage, critical hits, attack speed, range, regeneration, Thorns and more. Unlock new rows as your defense grows, revive your throne with Charon's Refusal, and watch your idle tower defense climb from wave 1 to wave 10,000 and beyond.

COLLECT RELICS OF POWER
Unseal reliquaries to build a collection across five rarity tiers, from common Arcadian relics to world-bending Primordial mythics. Legendary relics grant real mechanics: execute weakened foes, slow the horde, detonate the fallen.

MYTHOS AND TRIUMPHS
Recover every god's lore, fragment by fragment, by using their blessings in battle, and earn a permanent boon with each one. Claim Triumphs for every milestone of the siege.

CLIMB THE LEADERBOARD
Push your best wave onto the global top 100 and prove you can outlast the world.
