KristalisTower defense × survivor
Dive into the swarm with your hero, build and merge towers, and defend the crystal core against wave after wave.
While your towers guard the core, your hero roams the field, mows down the swarm and levels up. Every level plays out in a new arena.
Archer, ice, poison, tesla, cannon, flame and laser: merge two of a kind to unlock a stronger version. Flame and poison, laser and tesla fuse too.
While the towers guard the core, steer your hero into the swarm: swing the sword, level up, earn talent points.
Ring Keep, Twin Lanes, Twin Cores, the Maelstrom… rotating through seven regions from Green Vale to Void Shore.
Waves grow stronger forever. Pick your map, beat your record; how long you last goes on the leaderboard.
45 items across four rarities. The odds for every chest are shown in the shop — just tap ⓘ.
Daily and weekly quests, and a new Season Pass full of rewards every season.
Every boss has its own ability kit: the Titan slams the ground, calls down meteors and raises a shield; the Lich King teleports and summons help. Place your towers accordingly and step in with your hero.
Six gear slots from weapon to boots: equip what drops from chests, merge matching items to raise their rarity. Every hero level grants 3 talent points.
Everyone starts in Bronze and moves up at the end of the week based on their rank. In endless mode, the longest survivors get a board of their own.
From the Crimson Desert to the Lava Fields: battle, boss, endless and leaderboard screens, plus the hero and menu screens (these two in Turkish).
