About This Game

AsterMaster is a beat-driven roguelite shooter on a hex grid. Everything on the grid moves to one metronome: enemies step and strike on the beat, you step with them, and a shot that lands on the beat bites harder. Dig into a dead mining asteroid, break what guards it, and haul your ore back out alive.

HULLS THAT BREAK WHERE YOU HIT

Bosses, elites and your own ship are built from Gaussian splats: about five thousand glowing shards and a hundred chunks each. Every hit carves a real crater where it lands, and each damage type leaves its own mark. Strip the plating and chunks tear off. When a boss crosses a damage threshold, its most battered part breaks away for good. The destruction core is native C++, so the shards fly at full frame rate.

SEVEN CHAMPIONS, ONE PART AT A TIME

Elite enemies with destructible hulls — Pack Alpha, Battery, Bastion, The Eye, Shepherd, Hive Mother, Sower. Each run rolls its own three from the seed. Which part comes off depends on what you shoot with and from where: a direct shot takes the nose or the stern, a mortar shell caves in the top. A champion missing a part fights differently.

EVERYTHING MOVES ON THE BEAT

Every attack is telegraphed on the hex grid. Read the pattern, step into the gap, fire on the downbeat — off-beat volleys ricochet off armour. Take hits and your Neuro-Link degrades… run it red-hot for a comeback. A checkpoint at every arena gate and one Reconnect per run.

DIG DEEP, GET OUT ALIVE

Every run is an expedition across a procedural mine graph: surface zones, boss-gated descents down to the crimson depths, and orbital fragments where smugglers pay extra for your ore. Drilling makes NOISE — the deeper you strip the asteroid, the harder the swarm pushes back. Clear a segment and the asteroid itself splits apart beneath you. Bank your cargo at a station, or gamble it on one more descent.

BUILD A MONSTER

15 weapon mods, 3 slots, modifiers stack up to ×3. Four barrels — sniper, railgun, mortar, cutter — and eleven modifiers: thermite burns, ricochet volleys, cryo blocks, gravity wells. Mods of one archetype fuse into synergies that reshape the whole run. Eight powerups on top: an innate blink-dash, auto-block, arc coil, a holographic decoy. Between runs, feed cores into a meta-tree: new mods, powerups and synergies, a fourth mod slot, a bigger cargo hold.
