Corevia: Power Grows Over Time

Merge towers, grow stronger over time, and hold the line in idle defense battles

Corevia: Power Grows Over Time is a strategic idle merge defense game where patience, smart merging, and constant upgrades lead to unstoppable power.
Begin with basic towers and merge two identical ones to create stronger defenses. Each merge increases damage, attack speed, and unlocks new abilities that help you withstand endless waves of enemies.
Tap on towers to collect coins and invest them into upgrading stats, boosting your entire defense line. Unlock up to 30 unique tower types, each with different roles and power levels, allowing you to experiment with diverse strategies and optimized builds.
As time passes, enemies become stronger, faster, and more numerous, forcing you to carefully plan every merge, upgrade, and placement. Even when you’re offline, your towers continue to fight automatically, earning rewards through idle progression.
With simple controls, satisfying merge mechanics, and endless growth, Corevia: Power Grows Over Time delivers a relaxing yet deeply strategic defense experience.
Merge. Upgrade. Grow stronger—because power never stops evolving.
