Alien: Blackout is a mobile game, that released back in January 2019, and pseudo-sequel to Alien: Isolation. It's available for iOS and Android devices via the Apple App Store and Google Play Store respectively. However, it's usually a premium game (meaning you would have to pay for it). Not today, though!
Since it's Alien Day today, a day which celebrates the iconic and terrifying multimedia franchise (which began with Alien all the way back in 1979); the Alien: Blackout mobile game is available for free! You can pick up a copy from all of the aforementioned devices and digital storefronts. What's more, it seems you will be able to keep it indefinitely.
You pay as Amanda Ripley, the daughter of Ellen Ripley, and must guide the four crew members of the USCSS Haldin through several levesl of Weyland-Yutani's Mendel Station. Of course, there's an unpredictable Xenomorph creature in your way. Not to mention power outages and the like which the player must strategically manage.
After today, Alien: Blackout will revert back to it's usual price of $4.99. So, be sure to pick up a copy while yo ucan! You can check out the announcement tweet below from the mobile game's official Twitter account (via @AlienBlackout):
