Remaking a game from a now defunct studio?

I’m already well aware of remaking a game from another studio to be copyright infringement without permission. However, what about games from a studio that no longer exists?

To be specific: Battletanx: Global Assault is the game I want to bring to Unreal. But with the company 3DO out of business and no way to contact anyone obviously I can’t get permission.

BUT with the studio out of business (not even becoming another company, end of the line COMPLETELY) what happens to the copyrights/trademarks?

While we can’t give you any legal advice here, we can say that it’s possible for another company to have picked up the rights to that IP.
