Streets of Rogue released in 2019 and it's one of my absolute favourites from last year (still is this year to be honest with you, it's just that good). The developer, Matt Dabrowski, recently outlined their future plans which will include a sequel.
The 2019 release was after over six years of development, and at least half of that it was available in some form to the public. First as a free taster and later a full game. In an announcement on Steam about the latest update, Dabrowski mentioned how they would like to "take Streets of Rogue in some big new directions" and so they've "decided to begin work on a sequel".
I can't tell you just how excited I am at the idea of all the gameplay mechanics from Streets of Rogue, placed into a bigger world. Oh the possibilities! Just look at how ridiculous and fun it can be already:
Speaking to Dabrowski today about the sequel and Linux support for it, they mention to me that they "don't see why the sequel wouldn't appear on Linux" as long as Unity doesn't cause them "any horrific technical issues". However, they were keen to mention that it's "a WAYS off" as they've barely even begun on it.
