Smack Studio

Smack Studio is a sandbox fighting game paired with powerful built-in creation tools. Its standout technology turns 2D sprites into 3D animations with real depth and rotation, mapping flat images onto bones in a 3D skeleton, and automation tools speed a character from concept to playable creation.

Battle Mode supports eight-player offline versus and four-player online play with rollback netcode, against friends or CPU opponents. It ships with a base roster of 16 characters and 23 stages, plus a hidden one, and offers fast, competitive play with high combo potential and player-created ultra attacks. It works with DirectInput and XInput controllers, including GameCube pads through an adapter.

The character editor lets you build pixel-art animations frame by frame, attach art to an animation rig, create custom projectiles and special effects, and add simple coding through actions on animations, taking a character from idea to playable in under 30 minutes with templates. Steam Workshop support shares creations, and you can export animations for your own projects, since the developers hold no claim over IP made in the tool.
