The game actually released for Windows in March of last year, but it seems it completely flew under our radar as they added Linux support later in May. Annoyingly, Steam still doesn't add-in newly released games for Linux into the newly released list. Hopefully Valve will fix that one day.
Anyway, it sounds like an interesting game to be inspired by two titles that are so wildly different has caught my interest.
