Absolver is an "online multiplayer combat RPG" that, to me, looks like Bushido Blade meets Zeno Clash (and if it's not that, could someone make that, please?) It was announced a few months ago, and it's not got any less enigmatic since, even with the release of a new trailer at the PlayStation Experience yesterday.
The Sloclap-developed, and Devolver-published game is still on track for an unspecified 2017 release, and you'll be pleased to hear that it's "coming first to PS4 with exclusive content". Boo-urns! Does that mean it'll be on PS4 before Xbox One, or on PS4 before Xbox One and PC? It's a bit unclear, but hopefully that "exclusive content" is little more than a bunch of inconsequential fluff like Crash Bandicoot and Kratos masks or something.
Regardless, Absolver is still looking fab. Here's a short trailer confirming that:
