Dune Legacy has mostly the same gameplay of the original game, but adds a modern interface, including multiple unit selection, building queue, zoomable graphics. Some new features, such as fog of war, are optional. The most notable differences in gameplay are: * Infantry can be freely combined in 1-5 men units. * Ornithopters do not attack automatically, they can float in midair and be fully controlled by the player like other units. * Buildings and slabs can be placed one square away from other buildings and slabs.
