Fortress of the Fallen
SteamDefend your kingdom in a compact medieval tower defense experience where preparation is everything.
When the sun rises, you expand your settlement, manage scarce resources, and shape your defenses.

There are no endless systems to babysit. No bloated mechanics to memorize.
Just planning, pressure, and survival.
Build arrow towers, artillery, and military structures. Reinforce your walls, choose where to invest, and adapt as enemies grow stronger with each passing night.
One poorly placed structure can break your entire defense. Smart preparation is the only path to survival.
