Explorers of Sky, the enhanced version of Explorers of Time and Darkness before it, is renowned as the peak of the series in terms of both content and storytelling. For those wanting to re-experience this stellar title in a new light there's some good news, though not from Spike Chunsoft or the Pokemon Company.
Pokemon Mystery Dungeon: Explorers DreamNexus (shortened to DNX) is a fan-made ROM hacking project for Rescue Team DX that's attempting to bring an enhanced Explorers title to the Switch, using the DreamNexus editor by techtinks. The first trailer for the project released yesterday, with a demo containing Chapter 1 planned to launch later this year. In the trailer you can see parts of the game's opening including a new starter selection with fourth generation Pokemon, the Beach Cave dungeon, and a brief glimpse of Treasure Town and its inhabitants.
