In Giants: Citizen Kabuto, players take on the roles of three humanoid races: gun-toting Meccaryns, magic-wielding Sea Reapers, and the gigantic Kabuto. Each player is assigned direct control of a single character. The game's developers, Planet Moon Studios, created this design to encourage players to focus on the action and not to be burdened with micromanagement. Players can customize the controls, which are largely the same for each race, with slight differences for abilities. The single-player mode consists of a sequence of missions set as an overarching story. Each mission requires the completion of certain objectives to progress to the next mission. The objectives are usually the elimination of enemies or a certain structure, but several of them test the player's eye–hand coordination or require the player to rescue and protect certain units. Players control their characters from a default third person perspective; a first person view is optional. Each race has its own offensive style, and a special mode of fast movement. Killing a creature releases a power-up, which heals or awards weapons to its collector.
