Smash treasure chests and overwhelm enemies with a shower of items!
Chest Buster is an incremental/idle combat game where you fight by destroying only treasure chests. Instead of hitting enemies directly, smash the chests in front of you. Items dropped from destroyed chests immediately boost your power without any inventory management. The higher the chest level, the more powerful the items that drop!
Upgrade your skills for explosive destructive power!
Use coins earned in battle to unlock new destructive weapons from the skill tree to smash chests more efficiently. Upgrades not only increase attack speed and power but also increase the number of chests, allowing you to gain even more loot. These skills and weapons are permanently retained even if you fall in battle, making you stronger with every repetition!
Aim for massive rewards with card flips and slot machines!
It's not just pure luck. It's a strategic system where you upgrade your skill tree to directly control your reward probabilities. Acquire explosively dropping loot and gain overwhelming firepower!
Eliminate enemies forever!
Completing the mission permanently removes that enemy and grants you permanent rewards!
Give traits to chests and create your own unique build!
Research various trait runes and combine them with chests to gain even more massive destructive power.
Arrange the runes to match your preferred style and complete your own build with optimal efficiency!
