As far as I know, SK has a Linux version. However, my account is hooked to my Steam. The problem is, it is marked as Windows and Mac only. How do I get around this and actually download and play on my laptop? I am running Ubuntu 13.04.
Currently there is no Steam version of Spiral Knights for Linux systems. If you want to use Steam to play Spiral Knights you will have to use Windows or OS X as your operating system.
