About Marrowsteel

HOLD THE LINEBehind you — the last human cities. In front of you — a swarm that never stops.A LIVING SWARMHundreds of biomechanical horrors surge forward as one living mass to tear through your defenses — so where a tower stands matters as much as how it's built. And bosses change the fight: the first one walks in under an energy dome that shields every bug around it.MODULAR TOWERSYou can't buy the ultimate tower — you build it, module by module.

Mount a heavy barrel, load armor-piercing rounds, strap a second gun to the mount. Every part changes how the tower fights, and every choice costs you somethin FEATURESModular towers - every build is uniqueHundreds of enemies moving as one swarmBosses with their own mechanicsRoguelite runs A persistent research tree that grows with the towers you playYou might enjoy Marrowsteel if you like...
