About Alien Quarantine
Alien Quarantine turns this tab into a shooting game session. Nothing installs, nothing tracks you across the school network, and nothing stops you squeezing in one more run before the bell. Expect alien, levels, shooter — with controls you'll have down by the second try.
Like every title on Unblocked Games 77s, it streams straight from its publisher's servers — you always get the current version and nothing is ever installed on your device. Finished this one? Alien Wreckage is next on the same shelf.
How to Play Alien Quarantine
Controls: WASD move, mouse aims, left-click fires
Press the Play button above and the game loads inside this page. The first load carries the assets; after that your browser caches them and every restart is nearly instant. Use the fullscreen button when the action deserves your whole screen.
Tips Before You Press Play
- Short sessions beat marathons: muscle memory locks in between plays, not during them.
- Treat run one as a scouting mission — learning what ends your run beats chasing a score you can't keep yet.
- Reset bad runs instantly. Two seconds of restart always costs less than two minutes of a run you've already lost.

Alien Quarantine — FAQ
Is Alien Quarantine free to play unblocked?
Yes — Alien Quarantine runs free inside this page on Unblocked Games 77s. Nothing to download, no account to create and nothing to pay, ever.
Can I play Alien Quarantine at school?
The game is standard HTML5 delivered over HTTPS from unblockedgames77s.com, so a network filter sees an ordinary web page rather than an app. That's why it usually loads where big gaming portals are blocked — your school's own device rules still apply, of course.
What device do I need for Alien Quarantine?
Any up-to-date browser: Chrome, Edge, Firefox or Safari on Windows, Mac, Linux or Chromebook. A keyboard and mouse give the smoothest run.
