About Crystal Guardian
Defend the last crystal on the planet in Crystal Guardian! Build turrets, upgrade defenses, and fend off waves of mining robots while tackling 10 challenging boss levels.
How to play
1. Choose the Press Campaign mode and select a spot on the map, or dive into Endless mode. 2. Foes will dash towards the central crystal along the routes — tap (or click) them to inflict harm. 3. Eliminating enemies earns you points and shards which can be spent in the shop: turrets fire automatically, the auto-laser zaps adversaries, and upgrades enhance your tapping prowess. 4. Ice halts all enemies briefly, while Nova deals damage and sends them flying back. 5. Ensure enemies don't reach the crystal — if its HP hits zero, you'll lose. 6. After each wave, pick one upgrade card from three options. 7. At the end of each location, a boss with unique abilities and a second phase will challenge you. 8. Clear locations to unlock new ones and upgrade Crystal Memory — its benefits apply to every playthrough. 9. In Endless mode, mutations emerge starting from wave 5, offering greater risks and rewards.
