The Hollow Tower

From itch.io: Zenith City was to be a monument to the State and its people, a modern, master-planned metropolis raised up out of the bare desert. But halfway through, the project collapsed and it was abandoned, a partially-built, dust-covered hulk hundreds of miles from the nearest populated area. At its center lies what was to be its crown jewel: Tangram Tower, a concrete and steel spike jutting 150 stories into the sky. The officially circulated story is that the project turned out to be too expensive, and the State, loyal above all to its people, abandoned it as a waste of resources. But for some time now, rumors have whispered of a military lab high in the Tower, some kind of strange, ambitious weapons program that the army kept off the books. To those scavengers and spies ambitious enough to venture in, it’s a tantalizing opportunity.
