Key # Yes This feature can be constructed, with minimal (if any) limitations. Partial Support This feature can be constructed, but not in all instances. Details will be given as to what is/is not possible. Partial support could be due to intentional design reasons (including realism or general infeasibility), or simply because the feature has not been fully developed. Limited Support This feature can be constructed, but only in extremely limited circumstances. Instances that are possible may be listed, insofar as it is possible. Use at your own risk. No This feature cannot be constructed. This restriction could be due to intentional design reasons (including realism, general infeasibility, or game limitations), or simply because it has not yet been developed. — This feature is not applicable.
OxO Stands for 'Orthogonal x Orthogonal', and refers to a situation where both networks are orthogonal (in a straight line) along the game's grid, intersecting perpendicularly (at a 90° angle) OxD Stands for 'Orthogonal x Diagonal', and refers to a situation where the base network is orthogonal (in a straight line) along the game's grid, and the cross network is diagonal (running at a 45° angle). DxO Stands for 'Diagonal x Orthogonal', and refers to a situation where the base network is diagonal (running at a 45° angle), and the cross network is orthogonal (in a straight line) along the game's grid. DxD Stands for 'Diagonal x Diagonal', and refers to a situation where both networks are diagonal (running at a 45° angle) along the game's grid, intersecting perpendicularly (at a 90° angle).
