In case you missed it, it was Alien Day yesterday. Sega sure didn’t, as they’ve given their games based on the Alien franchise a huge discount on Steam for the next 24 hours!

The bundle includes the seminal Alien: Isolation (which is 95% off), the not-so-seminal (unless you patch it yourself) Aliens: Colonial Marines and 2010’s Aliens vs. Predator.

Keep in mind that the sale is on until Tuesday, so if you haven’t had the chance to experience one of the best horror games of the past 10 years, then this is definitely your chance.

Alien: Isolation is also available on PlayStation 4, Xbox One, and more recently, the Nintendo Switch.
