Press J (or click both sticks in) and your Viking drops onto a board running Skate 3's real engine, with Skate 3's own sounds. Press it again and you're back in Valheim, right where you stopped.
What you get
Skate 3's actual physics, flick-it tricks, grinds and follow camera, riding Valheim's terrain, rocks, trees and everything you've built
Ledges, walls and beam edges around you turn into grind rails automatically
Your Viking is animated by the Skate 3 skater, on Skate 3's own skateboard
Triangle / Y steps off the board to walk, just like Skate 3
R1 / RB swings your board at Greydwarfs, Greylings, boars and trolls (never other players or your tamed animals)
D-pad Up: High Pump. D-pad Down: Dunno
Portals and water drop you safely back into Valheim
Skate 3's sound
Skate 3's own rolling that follows your speed, with the trucks rattling and wind at speed; built floors sound like wood, stone or iron
Pops when you flick a trick, flip and spin whooshes, and landings as loud as the impact
Grinds, boardslides, powerslides, reverts and Hall of Meat bails
Stepping off your board and getting back on
Clean, like in Skate 3, and it follows Valheim's sound-effects volume
Controls
Plays best on a PS5, PS4 or Xbox controller, with Skate 3's original layout. Keyboard works too: WASD to steer, arrow keys for flick-it, Space to push.
What you need
Valheim on PC
Your own copy of Skate 3 for Xbox 360 (the extracted folder with default.xex). Melty finds it on your PC and prepares it automatically the first time you press Play, sounds included.
