Warframe features both Jupiter and Europa.
Jupiter is one of the head manufacturing site for one of the game's factions, the Corpus. They are a profit driven money cult that focuses on proxy units for wars. There are massive cities/factories suspended on the atmosphere constantly creating new proxies and experimenting with new technologies.
Europa has been invaded by another faction in game multiple times, the Grineer. It was a war-zone. The planet is littered with Corpus ships that are buried under ice which the Corpus tunnel there to reclaim the wreckage for parts.
