Rust & Thunder

The last fortress stands. Make it count.

Rust & Thunder is a dieselpunk tower defense roguelite for one hand. Your fortress holds the bottom of the screen; wave after wave of war machines, alien insects and the walking dead march down from the top. Your guns aim and fire on their own. You decide what to build, what to upgrade and when to take a risk.

BUILD YOUR FORTRESS
Start with a concrete bunker and a single machine gun. Between waves, pick one of three upgrade cards: install new weapons, raise their level, reinforce the walls or bend the odds in your favour. Every run plays out differently.

SIX WEAPONS, EACH WITH TWO EVOLUTIONS
- Machine Gun: becomes a spinning gatling.
- Heavy Cannon: armour-piercing shells that turn into siege artillery.
- Artillery Mortar: long-range barrages that flatten whole columns.
- Tesla Generator: lightning that jumps from enemy to enemy.
- Flak Cannon: curtains of shrapnel against everything that flies.
- Flamethrower: a wall of fire, and napalm that keeps the ground burning.
Weapons evolve at levels 5 and 10 and change how they look, sound and fight.

THREE ENEMY FACTIONS, FIFTEEN BOSSES
- The Iron Swarm: walkers, tanks, bombers, shield carriers and repair drones.
- The Hive: zig-zagging ants, skittering spiders, leaping beetles and acid spitters.
- The Revenant Legion: dead soldiers who rise again, gas that chokes your guns, and a walking bell tower.
Every tenth wave a boss arrives: from the Iron Behemoth to the World Engine, the Brood Colossus and the Charnel Titan.

PERMANENT PROGRESS
Every run earns research points. Unlock new weapons and weapon platforms in the research tree, grow your fortress through five stages from bunker to Ironhold, and chase achievements and your best wave.

MADE FOR PHONES
- Portrait, one-handed, short runs you can pause at any time.
- Hand-crafted pixel art in the spirit of the classic 16-bit action games.
- Plays without a connection.

FAIR TO PLAY
Ads are always your choice: watch one for a bonus, never forced into a fight. War Bonds buy colour schemes for your fortress and weapons; they never change a single stat.
