It also has three prominent, completely new features - the height level of the toggled radar (in the Z-axis), and orthogonal and perspective projection modes.
(The steel deck-plate-and-ribs system may be idealized for analytical purposes as an orthogonal-anisotropic plate, hence the abbreviated designation “orthotropic.”)
Orthogonality - each capability to be independent of other capabilities and freely combined with other capabilities wherever meaningful.
Players move one man per turn to a vacant point one step in any direction orthogonally or diagonally.
