Overview
Marrowsteel is a tower defense roguelite in a grim sci-fi world. Build towers from modules. Unlock. Upgrade. Hold the line against the swarm.
Description
Behind you — the last human cities. In front of you — a swarm that never stops.
Hundreds 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.
You 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
Modular towers - every build is unique
Hundreds of enemies moving as one swarm
Bosses with their own mechanics
Roguelite runs
A persistent research tree that grows with the towers you play
Thronefall, Sir, We Have an Orc Problem, They Are Billions, Diplomacy is Not an Option.
