Missions are given by various Cartoon Network characters around the game world, who usually cluster around travel hubs. The main focus of the game is the completion of missions.

After leaving the first level, they can choose between four guides: Ben Tennyson, Edd, Mojo Jojo, Dexter. The player is guided in their quest by a specific character, beginning with Dexter's computer, Computress. Instead, they gather a loose analog known as fusion matter (which has multiple purposes) through defeating enemies and completing missions, and upon collecting enough can perform a mission to raise their level, but as of February 16, fusion matter acts more like experience as players can now perform multiple nano missions every four levels. Unlike ordinary role play games, the player does not gain experience in the conventional sense. The player is provided with various weapons to accomplish this, including ranged and melee weapons. Gameplay primarily focuses on accomplishing missions. The game has large playable environments, with travel facilitated by various warp points. Their character is viewed from a third person perspective, viewing the HUD, and the range of movement consists of walking in any direction and a short-distance jump. In Fusionfall, the player takes control of a customized avatar.
