Shimmerkeep

Shimmerkeep is a free crystal tower defence. Waves march along winding paths toward your crystal core. Build towers on the grid, upgrade them, link them into combos and hold the line.

Features

• 100-level campaign with a boss every ten levels and up to three stars to earn on each level.
• 6 maps: Crystal Vale, Glimmer Steps, Shard Hollow, Prism Coil, Heartstone Lattice and the fourteen-turn Aether Spire.
• 8 tower types: Single, Splash, Slow, Sniper, Frost, Beam, Mortar and Aura. Each has three levels. Sell any tower for a 70% refund or swap it for another type.
• 15 enemy types and 10 bosses. Wardens harden nearby foes. Aegis block their first three hits. Geodes shatter into a swarm. Flickers blink down the path. Prisms can't be slowed. Obsidians shrug off weak hits.
• Tower combos. Five pairings boost towers built close together. Link lines show when a combo is active.
• Endless mode unlocks after Level 10. Clear waves 10, 25, 50, 75 and 100 for milestone rewards.
• Daily challenge. Every player gets the same 15-wave run on a given date, with one of five twists. Keep your streak going.
• Local high scores. Your top 10 Endless runs and top 10 Daily runs are kept on your device.
• The Keep. Every run, won or lost, earns shards. Spend them on permanent campaign upgrades and pick one path: Focus Fire, Efficient Builds or Extended Range.
• Tower mastery. Your towers grow stronger the more enemies they defeat in the campaign. Endless and the Daily stay on even terms for everyone.
• Easy to pick up. A short Level 1 tutorial you can skip, a one-line explanation the first time each special enemy appears, and placement that asks for a tick before it spends your gold (you can turn that off).
• Options. Volume sliders, mute, particles, reduce flashing, 1x / 2x / 3x speed and keyboard shortcuts for building, starting waves, upgrading, selling, speed and pause.
