Free alien games on Android range from spot-the-impostor hunts like Find the Alien to arcade space shooters, an idle game where you play the alien and a tower defence game. Three listings mention offline play. Several are rated Everyone 10+ and one is rated Teen, so check the label before handing a phone to a younger child.
Little green visitors have been a gaming staple since the earliest arcade cabinets, when rows of invaders crept down the screen. On a phone they've branched out into detective games, idle games and base defence.
To build this list I looked at each game's Google Play page and noted the developer, installs, content rating, the ads and in-app purchases labels and any offline wording. No game is ranked above another.
One pattern stands out straight away: every single listing carries both the Contains ads and In-app purchases labels. That's normal for free arcade shooters, but it's worth knowing before you start.

Which kind of alien game suits you
Space shooters are the biggest group here. Galaxy Attack, Space shooter - Galaxy attack, Galaxiga, Raiden Fighter and Universe Invader all have you piloting a ship against waves of enemies, and they're perfect for a few minutes of quick reflexes.
Find the Alien and its sequel are slower. You're looking for impostors, which feels more like a puzzle. Alien Invasion lets you be the invader, Aliens vs Zombies is about planning defences, and Aliens Drive Me Crazy puts you behind the wheel.

One thumb, one ship: arcade shooter tips
- Keep your thumb slightly below the ship so you can see it.
- Move in small slides rather than big swipes.
- Collect upgrades early, before the waves get busy.
- Watch the edges of the screen, where enemies often slip in.
- Take a break when your thumb starts to ache.
Age ratings on the alien list
Six of these ten games are rated Everyone 10+ on Google Play, three are rated Everyone and Aliens Drive Me Crazy is rated Teen. If you're choosing for a younger child, the Everyone-rated shooters are the place to start, and it's still worth playing a level yourself to see how the ads behave.
Spooky co-op and light downloads
If you love the creepy side of alien stories and play with friends, there's a separate list of co-op horror games to play together that goes well beyond phone shooters.
For phones with little room to spare, this guide to light offline open world games for low-memory phones is a good next step.
And if you'd like alien shooters on a bigger screen, this explainer on downloading free PC games without hidden extras helps you avoid sketchy download sites.
Playing aliens without a signal
Only three listings here mention offline play: Alien Invasion, Raiden Fighter and Aliens vs Zombies. For the rest, open the game with Wi-Fi off at home before a trip, so you know what happens when there's no connection.
Where I'd begin with alien games
If you like puzzles, start with Find the Alien. If you want classic arcade action, pick any of the space shooters and keep the one whose controls feel best. For long journeys, look at the three games whose listings mention offline play.
