It looks like uh, an old school single player swordfighting platformer. Like Zelda 2 or Prince of Persia 2, or Faxanadu, or Super Probotector if you had swords instead of guns, perhaps even a bit like Golden Axe (just no 2.5D terrain or grid or whatever it is called).
It will be released in September as far as I understand, yet there are already "100% completion" videos out. Some, errmmm, kind of time travel I suppose? Anyway, prolly dont watch those as they prolly contain spoilers (I wouldn't know because I didn't watch those since I don't want to ruin the experience). I recommend watching only the launcher trailer that is 1 minute and 41 seconds.
It will be out for the Nintendo Switch and with a bit of luck you can get one of those for 150 euros on Facebook market place or whatever. Of course, the point of the game is the offline multiplayer aka "buddies in your sofa", so you still need three more controllers, and the cheapest of those (third party unofficial of course) are like 25 euros each off amazon. So thats 150 euros + 75 euros for three extra controllers + 50 euros for the game itself. But if you got the money it will be worth it. I think. Still haven't played it ofc, need to wait until September for that.
Anyway, go watch the launcher trailer if you think it sounds interesting
