The macOS version of Rise of the Tomb Raider: 20 Year Celebration arrived a couple of days ago, and after a short delay the Linux version has now followed suit as well. Since the name itself isn't exactly descriptive, it is worth mentioning that the 20 Year Celebration edition brings with it the full Rise of the Tomb Raider game and all of the DLC. 

As far as the port itself is concerned, both the macOS and Linux versions have not been made by the original developers, but rather by Feral Interactive. If the name doesn't ring any bells, you might know them from their work on the ports of Tomb Raider, Total War: Warhammer 1 and 2, XCOM 2, Dawn of War 3, and the list goes on. From what I can tell there have been very few complaints about the macOS version, so chances are the Linux port will be a decent one as well.

If you already own a version of the 20 Year Celebration on Steam, you will now be able to access all three without any additional payments. In other words, if you own the Windows copy for example, you can simply download and play the Linux and macOS ones as well. I genuinely don't know if your save files will carry over, but it's still a nifty little feature.

You can learn more about Rise of the Tomb Raider, as well as what exactly the 20 Year Celebration edition has brought to the table, by heading over to Steam. And finally, allow me to leave you with the official trailer, just for good measure. Enjoy!
