Supplice is currently (as of 2023-10-26) for Windows users, but thanks to the awesome work of the gzdoom team, and because there currently seem to be no engine code level changes, it is possible to play Supplice on Windows or Mac! Keep in mind, these instructions involve some work in the terminal on these operating systems, and assume you have some basic familiarity working inside of one. If you aren't comfortable with digging into some CLI shenanigans, it would probably be best to wait for an official release for your platform, and to request that the Supplice team add support for your platform.
The overview of steps is as follows:
- (Arguably most importantly) Buy Supplice!
- Install GZDoom for your platform
- Install steamcmd for your platform
- Use steamcmd to force install Supplice on your computer
