Free space invaders games on Android are vertical shooters where alien waves drop towards your ship and you blast them before they reach you. The ten here are free on Google Play, and two listings, Atlantis Invaders and Sky Champ, say they play offline. All show ads and in-app purchases labels.
Rows of pixel aliens shuffling left, right and down, getting faster as you pick them off. If you've played an arcade cabinet, you know the feeling. Phones turned that idea into a whole family of shooters.
The games below are invader-style shooters from Google Play, not the original arcade release. I read each listing and noted the developer, installs, the ads and in-app purchases labels, the content rating and any offline wording. They're in no set order.
Most of these modern versions add things the old cabinets never had: ship upgrades, boss fights and screens full of bullets. Your thumb drags the ship instead of a joystick.

The ten invader games
Space shooter - Galaxy attack
The biggest name here, with more than 100M installs. Its listing sets up the classic story: aliens have attacked, your squad is beaten and you're the last ship standing.
Galaxiga: Galaxy Arcade Game
A modern arcade shooter from 1SOFT with waves of alien invaders and starships to upgrade. It's rated Everyone 10+, the only one on this page that isn't plain Everyone.
Galaxy Attack: Shooting Game
ABI Games' shooter casts you as Earth's last hope against alien swarms. The listing promises a stiff challenge rather than an easy ride.
Falcon Squad: Action Shooter
Also from 1SOFT, this one says it draws on shoot 'em up and bullet hell games, with power-ups, fleet upgrades and boss battles.
Galaxy Invader: Alien Shooting
ABI Games' second entry, built around an alien army from another dimension attacking the border planets. You play a veteran pilot called back to defend them.
Atlantis Invaders
The odd one out: the invaders come from the deep sea, not the stars. Its listing calls it a deep-sea arcade shooter and says plainly that it plays offline.
Galaxy Shooter - Space Attack
Words Mobile's game describes aerial battles and waves of enemies in the shoot 'em up style. It has more than 10M installs.
Sky Champ: Space Shooter
Your ship takes the form of a fantasy animal here. The listing says it plays offline or online, with more rewards when you're connected.
Universe Invader 2: Alien War
A galaxy shooter from GCenter where you defend humanity against a relentless alien attack. It has more than 500K installs.
Space Invaders: Galaxy Shooter
OK Games' shooter, with more than 100K installs, casts you as a pilot protecting the galaxy. It's the only title here that uses the words Space Invaders.
Want AI doing the heavy lifting in your marketing?
I build the systems that handle the boring 80 percent, so you get your week back. Done properly, with the human kept in.
Classic invaders or bullet hell?
The original idea was simple: a slow march of aliens and one ship that fires a shot at a time. A lot of today's games sit much closer to bullet hell, where the screen fills with patterns and you weave through gaps. Falcon Squad says so outright, and others describe boss battles and swarms.
If you want the calmer, old-school pace, start early in any of these games, before the upgrades pile up. If you want chaos, push on to the later stages and the bosses. Either way, you'll learn quickly which kind makes you grin and which makes you put the phone down.
What the store labels tell you
- Ads: every game here shows a Contains ads label.
- In-app purchases: all ten have them, usually for ships and upgrades.
- Rating: nine are rated Everyone and Galaxiga is Everyone 10+.
- Offline: Atlantis Invaders and Sky Champ mention it; the rest are silent.
- Updates: most listings show recent updates, which is a good sign a game's still looked after.
Getting better at dodging
- Keep your thumb low so you can see your own ship.
- Stay near the bottom centre, where you've room to move both ways.
- Watch the bullets, not the aliens; the aliens rarely hit you directly.
- Grab power-ups only when the path is clear.
- Learn one boss pattern at a time instead of rushing ahead.

It's a shooter style where enemies fill the screen with bullet patterns and you dodge through the gaps. Falcon Squad describes itself that way.
