I bought it on Xbox 360 marketplace forever ago, and at some point, it disappeared from my games list and local drive. When I tried to re-download it, it no longer showed up in my purchases. This was a few years ago and before Xbox Live shut down for the 360, and all my other digital purchases were available, just not Syndicate.
Fast forward to now, and I can’t find the game available anywhere (Gog and Steam at least).
I remember it having an all-star cast (Brian Cox and Rosario Dawson, specifically) and some really cool game mechanics and story.
Did that game just get memory-holed? Wikipedia says it was banned in Australia, but that doesn’t apply to me.
Edit: There are used copies I can buy on eBay for the 360 (mine somehow still works) but I was looking to buy a PC version for longevity/future proofing since I like to revisit old games every so often and my 360 is already on borrowed time.
I just have a Linux-based “DIY Steam Machine” so it’d have to be able to run under Proton. I may just buy a physical disc on eBay for ~$22 and hope my 360 doesn’t crap out on me lol. It’s the later “slim” model with an upgraded hard drive, so as long as I can install it and it reads the disc enough to start the game, I should be okay.
Or you could pick up a cheap used Xbox One or Xbox One X. Anything with a physical drive.
For the DIY Steam Machine, yeah, what others are saying, disc image + emulation.
