Hold the roads. Keep the Spring. The elves of the Sylvan Reach are immortal only while the Everspring flows. Warlord Gorrak has marched the Iron Horde north to drink from it — an orc army that cannot die would wage war forever. You are the Warden of the Grove. Everspring is a free fantasy tower-defense game with no interstitial ads, no energy timers and nothing to buy. FOUR ROADS TO HOLD Wellspring Glade, Ashen Crossing, the Root Halls and the moonlit Moonwell Terraces — 20, 25, 30 and 25 waves, three difficulties, a Heroic version of every road, and Endless mode after the final wave, with optional curses for bigger rewards. SIX TOWER LINES, TWELVE SPECIALIZATIONS Ranger's Perch, Moonfire Altar, Grove Warden, Frost Well, Dawn Ballista and Spirit Beacon. Every tower upgrades twice, then forks into one of two specializations with its own ability: Windrunner Roost, Sunpiercer Bastion, Starfall Spire, Moonbinder Sanctum, Ancient Grove, Thornguard Thicket, Glacial Heart, Permafrost Shrine, Sunburst Engine, Siegebreaker, Warsong Beacon, Wellspring Shrine. A HERO YOU COMMAND Aelith Dawnwarden walks the roads with you: move her, block with her, fire her weapon's ability. Four weapons and four armors — bow, blade, staff and lance; leaf, bark, starweave and the Everspring Aegis — each with its own way of fighting. Legendary relics are earned by deed, not bought. ELEVEN ENEMIES AND A WARLORD Goblins, grunts, bat swarms, armored brutes, healing shamans, warg riders, sappers, berserkers, cave trolls, wyverns, Gorrak's shield-walled Champion — and Gorrak himself on the final wave. Armor, magic resistance, flight, healing and rage each want a different answer. EVERYTHING IS EARNED Every kill leaves Essence. Spend it in the Armory on towers, specializations, spells, permanent Wardenship upgrades and Aelith's gear. Reforge any relic up to three stars. Autosave between waves. Pause, 1×/2×/3× speed, call waves early for bonus gold. A NEW TRIAL EVERY DAY The Daily Trial: one road, one twist and one barred tower, the same for every Warden, new every day. Play it daily to keep your streak; the first win each day pays Essence. GAME CENTER LEADERBOARDS See where your Daily Trial score and your deepest Endless wave rank against Wardens everywhere. Made by one person. Plays offline.
