Dragonfall

The dragons of Skyrim have found Minecraft, and they've come to burn it. Within a minute of loading a world you'll hear a distant roar. Then a dragon wearing Skyrim's own scales swoops in, circles, and rains Fire Breath that sets forests alight and burns away the ground beneath you.

• Real Skyrim dragons: their roars, wingbeats, "Yol Toor Shul", death cries, skin and wings come from your own Skyrim Special Edition.
• Skyrim's music: the main theme on the menu, Skyrim's exploration tracks by day and night, and boss-combat music whenever a dragon is near.
• Dragon Souls and Shouts: slay a dragon, absorb its soul, and learn Unrelenting Force (Fus Ro Dah, press Z) to blast mobs and stagger dragons out of the sky.
• Hatch your own: every slain dragon drops a Dragon Egg. Hatch it and a baby dragon follows you around, breathing fire at hostile mobs.
• Peaceful friendly dragons: set your world to Peaceful and the invasion stops. Instead, friendly dragons drop by, land beside you, roar hello and leave a Dragon Egg. Feed one raw meat and it teaches you Unrelenting Force.
• Co-op for up to 8 players: your world opens to friends automatically and they join from Melty with one click, from anywhere. Dragons hunt the whole group; everyone earns their own souls, Shouts and baby dragons.
• Works in survival and creative.

You need Minecraft: Java Edition and The Elder Scrolls V: Skyrim Special Edition (each friend too). Melty sets up everything else.
