Alien Swarm: Orbit

How to Play Alien Swarm: Orbit

Controls

Click, tap or press Space to reverse your satellite's orbit direction. That is the only input — your turret picks its own target and fires automatically, so nothing depends on your aim.

Tips

• Treat reversing as a dodge, not a turn: flip the moment a bug enters your orbit lane, then flip back to reclaim your firing line.
• Your turret always shoots the nearest bug, so a leak is still recoverable — unless something closer keeps stealing its attention.
• Shields absorb one hit and shove the bug back outward. Spend them early; a saved shield has never stopped a Hive Queen.
• Every bug you destroy repairs the planet. Leaking is survivable, standing still is not — keep the turret busy.
• Chargers lunge at wherever you are standing. Hold your reversal until they commit, then slip past them.
• A Hive Queen arrives every third wave. She keeps spawning drifters while she advances, so clear the small ones first or the ring floods.
• Your combo now drives the gun — at nine in a row the turret fires at double the base rate and splits into twin barrels. Bank a few easy kills before a heavy wave, not during it.
• A leak or a hit drops the fire rate back to base instantly. When the orbit gets crowded, reverse early and keep the chain alive.

Frequently Asked Questions

Is Alien Swarm: Orbit free to play?

Yes — it is completely free, directly in your browser. No signup, no download and no install.

Can I play it on a phone or tablet?

Yes. It is built with HTML5 canvas and uses tap controls, so it plays the same way on mobile and desktop.

How long does a run last?

Most runs end between 60 and 120 seconds. The swarm accelerates every 22 seconds and a Hive Queen forces her way in every third wave, so the pressure climbs on a fixed schedule.

Do I have to aim?

No. The satellite fires by itself at the nearest bug. Your entire skill ceiling sits in when you choose to reverse direction.

Who made Alien Swarm: Orbit?

It is an original game developed in-house for 8204.me. Every shape, particle and sound effect is generated procedurally in code — no third-party art, audio or game engine is used.
