Our take on StackFortress

Instead of treating towers as fixed defensive units, the game makes construction itself part of tower defense. Block placement, component combinations, power distribution, and weapon heat become central to shaping each defensive structure.

What is StackFortress?

StackFortress is a tower defense game centered on free-form construction.

Players assemble defensive structures block by block, combining functional components with different roles, including mining, shielding, weapon systems, and power generation. A power grid supplies energy to connected components, making power management part of the defense. Hostile alien threats vary, requiring different planning approaches. Weapons can be overcharged by linking them to power injectors, increasing power use and causing overheating. The vendor also lists a cooling system as planned, involving radiators that would allow weapons to operate beyond normal capacity.
