If you’ve somehow missed the last few Twitch streams showing off the new co-op mode for Larian’s Divinity: Original Sin Enhanced Edition, then you might be wondering what all the fuss is about. Thanks to a trailer released today, those in the dark about the new mode won’t be anymore.

The co-op mode gives both players complete and total freedom and independence from each other, allowing friends to enter any area or initiate completely different quests without needing input or assistance from the other. The video does a great job of explaining this, as does the press blurb that accompanied it:

Explore a deceitfully vibrant world on your own or with a friend, together or independently in the same playthrough. When venturing together, you’ll share the same screen-space (with console-comfortable controls and UI!), but move apart when playing locally, and the screen dynamically and seamlessly splits allowing you to explore the entire world apart, without loadings.

Cooperative play adds a whole new dimension to Divinity Original Sin; from the turn-based battles giving prominence to teamplay, to quest resolution, exploration, dialogues, and the critical choices that will shape your adventure. Should you kill the Orc, or the Elf? Or none? Or maybe both? There’s always multiple solutions to any given problem in Divinity: Original Sin, and it’s up to you – and your friend, when you play in co‑op – to decide how to progress in your epic adventure. Of course, dissension may arise from time to time… don’t panic! Divinity: Original Sin incorporates an innovative game mechanic, inspired by a real-life ancestral problem solving remedy… rock-paper-scissors!

Friendships should be put to the test, and online griefing given a new arena, when the enhanced edition launches this October.
