Rust Spire is a 2D tower defense game with roguelite elements. In the evening desert, you build a tower from rusty debris: arrange blocks, guns, and rooms, and then repel the assaults of mutants and machines. The tower behaves according to the laws of physics — overloaded columns collapse dramatically, burying the enemies under the ruins.
Every 1–2 waves, you must make a choice: expand the base, increase firepower, or strengthen the structure. During the battle, active abilities use a shared energy pool: orbital strike, repair, overdrive, and emergency reinforcement.
The game offers 3 biomes, 60 waves, and endless mode:
• The Wastes — where you learn the basics;
• Acid Marsh — corrosion threatens your foundation;
• Frozen Frontier — frost mutes your weapons.
You'll face bosses with unique set-pieces and intelligent enemies: flyers, shielded units, and siege machines. Between runs, you can level up the Workbench meta-tree and adjust your loadout in the Arsenal. Death brings progress — you unlock countermeasures for whatever defeated you.
Daily challenges, leaderboards, and a choose-your-starting-biome mode are available. The game is designed for mobile devices and can be played with one hand.
How to play
In the construction stage, select a module card at the bottom and add a block adjacent to the core. Expand upwards and outwards: place weapons along the edges and modules for bonuses. Keep an eye on the load — overloaded columns will collapse.
During the combat phase, tap DEFEND to activate automatic weapon firing. Use energy for abilities like blast, repair, overdrive, and brace. Make sure enemies don't reach the core.
Between waves, adjust your strategy based on the threat, make repairs, and enhance your defenses. After each round, level up the Workbench. Controls are simple: just tap or use the mouse.
