Fortress Defense 2

Castle walls won't hold themselves. Fortress Defense 2 drops you into a relentless siege where your decisions matter more than your firepower. Waves of enemies push harder with each assault, and the gap between a smart deployment and a crumbling gate can be razor thin.

Heroes form the backbone of your strategy here. Each one brings a distinct fighting style to the field, and knowing when to hold them back versus when to unleash them separates veteran commanders from those who watch their walls fall. Weapon upgrades compound over time, turning modest defenses into something genuinely formidable — but only if resources are spent wisely.

The satisfaction comes not from raw action but from reading the battlefield, anticipating attack patterns, and building a defense that actually holds. Few things in browser gaming hit quite like surviving a wave you were sure would break you.
