Jump-start your game development with the Gunman Asset Pack! It has a fully rigged Spine skeleton and accompanying art that can be dropped directly into a game. The Spine project files are included, allowing the animations to be customized or new animations to be created as needed. The art can be completely replaced if a different style is required while still making use of all the animations.
While Asset Packs are useful no matter which runtime is used, as a bonus for Unity users each Asset Pack includes a Unity project loaded with features: character controllers, physics integration, sounds effects, and more. This project can provide a game’s entire foundation, freeing up resources to focus on gameplay, art, story, and other important aspects.
