The System Shock remake from Nightdive Studios was originally funded on Kickstarter, and after delays it was eventually released on May 30th, 2023 but two platforms have been missing - Linux and macOS.
Kinda shady considering this was a Kickstarter stretch goal.
Usually that’s because Linux versions have been abandoned after Steam Machines flopped. Same is with Dying Light, iirc Borderlands 2 as well
