Hold the crystal
Place towers along the path and stop every wave before it reaches the core.
Eight towers
Eight tower types, each with three upgrade levels. Frost, Beam, Mortar and Aura unlock as you go.
100-level campaign
A boss waits at the end of every ten levels. Clear a level cleanly for three stars.
Six maps
From the short Crystal Vale to the fourteen-turn Aether Spire, each with its own path.
15 enemy types
Wardens harden nearby foes, Aegis shrug off the first hits, Geodes shatter into a swarm, Flickers blink down the path, Prisms ignore slows and Obsidians only crack under heavy hits.
Tower combos
Some towers grow stronger when they stand side by side. Find the pairs that work.
Endless mode
Waves keep coming and keep getting tougher, with a boss every ten waves and rewards at milestones. Beat your best wave.
Daily challenge
A new run every day with one twist, the same for every player on that date. Keep your streak going.
Local high scores
Your ten best Endless runs and ten best Daily runs, kept on your device under the name you type.
The Keep
Every run, won or lost, earns shards. Spend them on lasting campaign upgrades and pick one of three upgrade paths.
Tower mastery
Towers you lean on in the campaign rank up and hit a little harder.
