Description
About This Game
One fighter. One dome. An army closing in.
Enemy ships link into constellations. Vast formations advance on your dome. Push into the crossfire, seize upgrades, then flash out in a streak of violet lightning. Return with enough firepower to turn the fight.Deep Space Siege combines roguelite builds, deliberate dodging, and base defense in a top-down space survival shooter. Weapons fire automatically; you control movement, timing, and upgrades. Both fighter and dome must survive. Push too far and you risk leaving it exposed; linger inside and the siege tightens.
Find the opening. Flash through it.
Read the warning, spot the gap, and burst through the barrage trailing violet arcs. Turn a desperate escape into an opening to attack.Return to the dome to restore your shield and recharge your dodge faster. Unlock consecutive flashes and other upgrades, then decide how far to press your next attack.
Build a storm of firepower
Choose your primary weapon before launch, then shape it with the upgrades you earn:- Pulse machine gun and scattergun: keep up a stream of suppressing fire, or close in for a spread of heavy hits.
- Thunder orb and photon railgun: spread lightning through the crowd, or send piercing shots down an enemy line.
- Missile launcher and drone swarm: cover targets in explosions, or send a growing squadron on strafing runs.
Support your fighter with defensive formations. Follow its branching skill tree to develop fire rate, projectile patterns, reach, and skill synergies. Watch your opening loadout grow into a screen-filling counterattack.
Fight enemies that turn the stars against you
Linked enemies form luminous constellations, sharing defenses and unleashing distinctive barrages. Troops assemble into formations and fire coordinated volleys. Rifts tear open to unleash charging hunters.Weave around the serpentine Azure Dragon. Face the spreading wings of the Vermilion Bird. Adapt your approach and dodge timing to find openings between colossal bosses' attacks.
Break the siege. Then test your limits.
- 24-stage campaign: collect salvage, invest upgrade points, and battle through armies and bosses to a finale of unfolding formations. Clear the campaign to unlock harder playthroughs.
- Endless mode: once unlocked, test your build against escalating waves, constellations, and rift ambushes. Upgrade choices pause the action so you can plan. Try another weapon, follow a different build, and chase a new survival record.
