Fifteen minutes. One base. Endless drones.
Your base is the last relay still on air. Hold out 15:00 against ever-tougher drone swarms and reinforcements clear the field. Let the base fall and the signal goes dark.
- Level up mid-fight — kills drop scrap that fills your level bar, faster as the run goes on. Each level-up freezes the battle and deals three cards: a tower, an upgrade, an augment or a bonus.
- No two runs alike — rushes, cards and buff pads change every run. Reroll a bad hand or skip it to repair your base. Pause any time.
11 towers, 22 modifications, 65 augments
- Autocannon, Pulse Tower, Vulcan, Railgun, Tesla Coil, Drone Pod, Rocket Battery, Laser, Amplifier, Ion Emitter and Satellite Uplink.
- One upgrade card levels up every tower of a type, even later builds.
- At Lv3 each type picks one of two modifications: Twin Barrels or Long Barrel, Focus or Sweeper, Gunships or Repair Drones that heal your base.
- 22 augments are exclusive to one modification, and each tower has a signature Lv5 attack.
- Rockets blast wide, Cluster scatters bomblets, HE Rounds spray shrapnel, laser and ion beams bend or split.
Shields, armor, hull: bring the right damage
Physical, Energy and Explosive damage hit Shields, Armor and Hull differently: energy cracks shields, explosives punch through armor, physical rounds shred bare hulls.
Bosses that change the fight
- Carrier — launches swarm after swarm.
- Overmind — hides behind link nodes and tethers your strongest tower.
- Colossus — fires seeker missiles, raises a barrier, then lunges at your base.
- Take down a boss for an Extra Pick: one more level-up card choice (two from the Colossus). Elites may grant one too, or repair your base.
- Elite wings bring Aegis, Splitter, Medic and Hacker drones. Golden Drones drop rare supplies.
Six bases, six skills
Each base has its own HP, main weapon and a skill on Space, from Signal Burst to Fire Mission. Two special bases bring Orbital Bombardment and Solar Flare.
Chase the combo
Chain kills through five combo tiers for bonus scrap, with hit-stop, debris and adjustable screen shake.
Grow stronger between runs
- Spend scrap on 7 research tracks, towers, modifications, bases and 12 perks (up to 4 per run).
- Each map you clear opens the next: the Canyon Transmitter, the Ruined Observatory, then Threat Tier II. Each map has its own terrain.
- 23 in-game achievements (2 hidden), each with a reward to claim: scrap, perks, augments, special bases.
- Every run is scored, and your best runs are kept under My Records in the lobby.
Easy to read, hard to master
- Flat neon shapes and light keep a full screen readable.
- Cards show which tower they belong to, with a compact stat block; the Hangar breaks down every tower.
- A short tutorial, concise tooltips, UI scale up to 145%.
- English, Korean, Japanese and Simplified Chinese. Made for mouse and keyboard.
