Build your own brawlers and battlegrounds, share them, and fight on a mountain mesa, in a big Forest, in a giant spooky Graveyard, on an asteroid in Outer Space or in a boxing ring — free. Type your name, pick your character (Human, Elf, Orc, Dwarf, Lizardfolk, Robot, or a 3D Adventurer, Explorer, Heroine, Ranger, Soldier, Grave Keeper, Skeleton, Vampire, Zombie, Ghost, Astronaut A, Astronaut B or Alien) and gender, then create every CPU rival yourself — there are no default CPUs: give each one a name, race, gender, look and fighting style (Balanced, Aggressive, Defensive or Sharpshooter). The Character Creator lets you choose colours, hairstyle and hair colour, head shape, headgear and a Balanced, Heavy or Speedy build, make your own signature move, pick a super move — Mega Punch, Shockwave or Meteor Slam — that unlocks once you've dealt and taken enough damage, and start with a blaster or grenades. CPUs are poor at getting back to the stage unless you give them Good recovery. Press 🌍 Share to let anyone use your fighter. Upload any animated 3D character (.glb, .gltf, .fbx). Build your own move — pick its animation and what happens when it hits (launch, stun, burn, freeze, pull, heal). Make your own item from shapes or an uploaded model and choose its power — it drops from the sky in your fights. You can also upload a model as a stage piece. Hearts, blasters and grenades drop mid-fight. The more damage you've taken, the further you fly — use your air jump and Recovery Rocket to get back to the stage. Play solo against up to 9 CPU fighters or grab a friend for local 2-player on one keyboard. Earn XP from every fight — KOs and wins give more — to earn keys, then open treasure chests to find one of 24 random Cube Pets that follow you into battle. Watch out: Goblins, Demons, Yetis and Giants drop into most fights, while Zombies, Ghosts, Skeletons, Vampires and Armored Skeletons rise only in the Graveyard — play as an undead character and they fight on your side. In Outer Space only Aliens spawn, plus a Rover that bumps you but does zero damage — play as an Alien and the aliens fight for you — beat them for bonus XP, or set Monsters to Off or Horde on the menu. Last fighter standing wins. Try 👾 Retro stages and fighters. New: 🗡️ Adventure mode — a Breath of the Wild-style 3rd-person open-world quest with sprint, climbing and stamina on a grass-tiled world with a sword, rupees, hearts, guardians, 3 Sun Shards and a final boss in the Starfall Crater; it earns XP too. R switches between your group members (Wizard, Sage, and ninjas you convince to join with F). Press M for the world map. Explore an enormous world and a safe, monster-free castle of many rooms whose chefs cook you meals. Keep your hunger up by fishing in lakes, ponds and streams (4 kinds of fish restore 4–7 hunger), and watch for the King, who wanders the land with three royal knights giving quests, while a Wizard friend heals you and blasts monsters.
