The game runs on the Divinity: Original Sin II engine, and is story-wise a more-or-less direct follow-up to that game, reuniting its six Origin Characters and the major NPC Malady in a new fight against the Bloodless. Gameplay-wise, it is a combination of Divinity: Dragon Commander's strategic gameplay and Original Sin duology's Turn-Based Combat, with you, as "the Commander", directing the main characters over the course of 60+ missions, which change considerably, depending on what you do.
The game contains examples of:
- Fantasy Gun Control: Averted for the first time in the series, with the Beast firing a musket in the announcement trailer, and the official website proclaiming that "gunpower comes to Divinity".
- Geo Effects: As per the norm for the Original Sin series, PAX gameplay showcases fields of elemental effects that change the battlefield in all sorts of fun (and often explosive) ways.
- Merging the Branches: In Original Sin II, you could only form a team of four and any of the heroes that you didn't bring would end up dead (in fact, at least two of them wound up killed, brought back as undead, then killed again). Here, all six of them are alive (or unalive) and well in the trailer.
- Vapor Ware: Originally planned for a 2019 release, the game's release has been delayed indefinitely. Promo material for Baldur's Gate III makes it appear that Larian has put the project on hold.
