The Odysseus Project is a follow-up to Star Cruiser. Gameplay concept and visual style are very similar to that of the predecessor: it is a first-person 3D shooter with extensive exploration and customization elements, which grants it a light role-playing angle. Much of the game is spent on planet surfaces, in populated or hostile areas. Combat is action-based by default, but there is an option for a menu-based combat as well. There is a variety of weapons, armor, gadgets, and items to find or purchase. It is also possible to physically navigate a spaceship. Combat in space plays similarly to on-foot battles, with the additional of a freely rotatable camera.
