Upgrades
Battle For Blockchain lets players further customize their experience in a collaborative way through Kingdom Upgrades. In this system, players can donate resources earned in battle to invest in specific units, enhancing their capabilities for everyone in the Kingdom.

Shared Experience
What makes this system unique is that upgrades are shared among all players within a Kingdom. Players must strategize together—deciding which units to prioritize and which to leave behind—shaping kingdom-wide tactics. However, these upgrades are contained within each Kingdom. Other Kingdom might focus on completely different units, leading to diverse strategies and dynamic conflicts. In Battle For Blockchain, battles unfold not only on the battlefield, but also within the ever-shifting unit market.
Collaborative Work
Upgrading units is costly—too costly for a single player to handle alone. It requires the collective effort of an entire Kingdom. Players must collaborate, using various means of communication, to align on a shared strategy and decide which units to prioritize for the war effort.
Enhancing Units
Units can be upgraded from base level 0 up to level 9. With each level, they gain a small boost to health and overall stats. Notably, at levels 3, 6, and 9, key stats tied to their abilities receive significant enhancements, making these milestones especially impactful.
A level 9 unit is vastly more powerful than its base version and often highly sought after. However, this power comes at a cost—its market price will rise significantly, making it a more financially risky choice. Players must be careful not to over-upgrade a unit, as it may become too expensive to field effectively.
