Catapult roguelite for Android

Siegebreaker

A catapult roguelite for Android: steer every shot in flight and bring the walls down.

In development

Pull back. Let fly. Bring the walls down.

Siegebreaker is played in one hand. Pull the sling, loose a shot up the valley, and steer it in flight: curve round the trees, ride the updrafts, thread the sky rings, then tap to set off its special right over the keep.

Every shot is yours to fly

Ten payloads, each with a flight and a special of its own: a boulder that slams straight down, a keg that splits into three, a glider that dives through walls, an auger that tunnels under them, a nest of hornets that hunts the patrols. Throw low and skim the road, arc it, or lob it high over the walls, and a forecast shows where it will go before you let go.

Fortresses that fight back

Knock out a pillar and the roof it holds comes down on the defenders. Bunkers shrug off a flat shot, flak towers shoot down a high one, gates open and shut on a rhythm, and living thornwalls grow back between shots. Ice, mud, cobbles and runestones change how a shot skips, slides and ricochets.

Twelve valleys to cross

Twelve acts, each a valley of its own with its own sieges, convoys and Citadel, and more than a hundred fortress layouts in all. Choose your road on a branching map: a merchant or a forge, a siege or a treasure convoy, then the Citadel.

A different run each time

Draft relics after each victory, from 31 in six families, and they change how your shots behave. Spend your gold on upgrades for the catapult and new shots for your quiver.

Five commanders

The Master Artillerist, the Goblin Sapper, the Sky-Marshal, the Wildcard and the Steady Hand each play differently: one is dealt a new hand of shots every fight, and one cannot steer at all and hits harder for it.

A Daily Siege

One valley a day, the same for everyone, with your best score kept. Optional challenge rules bring fortified walls, storms and night sieges, and there are career records, goals to earn and three campaign slots.

Short lessons and a practice range teach the sling, the steering and the specials. Camera shake and vibration can be turned down or off, and warnings and targets are marked with shapes and words as well as colour.
