What platforms will Shoot 'm Up be released on?
Initially only Windows and Linux, over Steam. We hope to soon add Mac to the list. If demand is there, we will try to get consoles such as PS4 and XBOX there as well!
How does the map / asset editor work?
Well, thats a difficult one. Its extended. It has a lot of hidden features (and bugs) and is yet to be documented. For now, you can ask Dutch or Dukesoft in Discord for help - we're happy to help!
