Overview
Rust Spire is a 2D tower defense with a roguelite heart. In a sunset wasteland you assemble a tower out of rusty scrap: place blocks, weapons and rooms, then hold back waves of mutants and machines. The tower obeys physics — overloaded columns collapse spectacularly, crushing enemies under the rubble.
Every 1–2 waves is a decision: widen the base, add firepower, or reinforce the structure. In combat, active abilities share a single energy pool: orbital strike, repair, overdrive and an emergency brace.
3 biomes, 60 waves and an endless mode:
• The Wastes — learn the ropes
• Acid Marsh — corrosion eats your foundation
• Frozen Frontier — frost silences your guns
Bosses with signature set-pieces and smart enemies: flyers, shielded, siege. Between runs, level up the Workbench meta-tree and tune your loadout in the Arsenal. Death means progress — unlock counters to whatever killed you.
Daily challenge, leaderboards, and a pick-your-starting-biome mode. Mobile-first, playable one-handed.
