01 / THE MISSION

A small colony.
A very big problem.

The frontier’s outposts are under attack. You’re the commander standing between an alien swarm and the colony’s last beacon.

Hold and drag defenses onto open grid cells in tactical clearings. Plan around roads and blocked terrain, preview your range, then send the next wave when you’re ready.

03 / DEFENSE PLATFORMS

The right tool.
The right placement.

Six platforms. Three ranks each. Start with Pulse and earn the rest through sectors 1.2–1.6. Bring unlocked defenses back to earlier missions and build your own combinations.

Helios Lance game spritePLATFORM 05 / RANK I — III

Continuous beam / UNLOCK 1.5

Helios Lance

Holds a steady solar beam on the leading alien in range, dealing continuous damage. Good against durable targets; the beam ends as soon as its target leaves range. Deals 75% extra damage to energy shields and prevents recharge while firing.

TACTICAL NOTE

Keep shielded enemies in range. Helios deals 75% extra shield damage and interrupts recharge while firing.

STEEL PLATE / PERMANENT ARMOR

Crack the armor.

Heavy creatures and mechs carry permanent armor. Rail rounds bypass it. Pair long firing lanes with cryo fields to keep tough targets under fire.

ENERGY BUBBLE / RECHARGING SHIELD

Keep the pressure on.

Shields absorb damage before the hull, then recharge after a break in combat. Helios deals 75% extra shield damage; continuous fire and afterburn keep recharge interrupted.

04 / COMMAND ON YOUR TERMS

All strategy.
Anywhere.

Leave the signal behind.

The entire Android game is bundled on your device. No internet connection, account, or trackers. Just you and the next wave.

Pick up the command.

Progress saves locally, with a checkpoint before each wave. Step away mid-battle and resume from the start of that wave.

Change the tide.

Call in an orbital strike when the line gets crowded. Pause to think, adjust battle speed, and upgrade or sell your towers.

Hear the frontier.

Three original planet scores, distinct enemy death voices, mechanical failures, and shield-break cues. Set music and effects independently, or mute either one.

Choose your pressure.

Easy offers more breathing room. Medium brings measured mixed assaults. Hard adds heavier squads and shielded reinforcements. Saved missions keep their original difficulty.

Discover your enemy.

The codex fills in as you encounter new enemies. Learn the defenses and counters of organic swarms, crystalline creatures, armored walkers, and shielded drones.

YOUR NEXT MISSION

Somewhere out there,
a beacon is still burning.

Take command of the last line of defense.

How does the campaign work?

Start at sector 1.1 on Kepler-186f. Clear sectors in order, then finish every sector on a planet to unlock the next world. Earn one to three stars based on remaining colony integrity. Six platforms become available across Kepler’s six sectors.

Can I play without internet?

Yes. The Android game includes its content, artwork, music, and effects on your device. It requires no internet connection or login, and your progress stays in local storage.

How do I build and upgrade?

Drag an unlocked turret from the tray onto an open grid cell, or select it and hold the map to preview placement. Adjust your position, then release to build. Quick map taps never spend credits. Tap a placed tower to compare current and next-rank stats, upgrade or sell; tap elsewhere to dismiss. Selling returns 70% of your full investment.

Can I change the difficulty?

Choose Easy, Medium, or Hard in Settings. Your choice applies to new missions; a resumed checkpoint keeps its original difficulty. Restart a mission to use your new setting. Stars count toward the same campaign progression on every difficulty.
