Planet Novus completed with 100% item collection. Metroid Planets is a highly impressive fan game, firstly presenting a fairly faithful remake of the classic NES Metroid, but going far beyond that in a remarkably complete package - as well as just some usability improvements while maintaining largely the same graphics and sound, there's an entire new campaign, completely remixing the game world with a significantly higher difficulty, a randomiser, new boss fights and much more. The gameplay still feels relatively basic when compared to later official Metroid games, but that's a deliberate choice to maintain a level of faithfulness; if you're looking for the classic Metroid experience, without the much more extensive changes introduced by Zero Mission, you won't find any better option than Metroid Planets.
