Bridges cost 10 bricks in this game. They can be built only at specific bridge points, indicated by a pair of 1x1 plates with a stud on top. Unlike other buildings, they can be built when part of the area they occupy is unexplored, and land units can walk on a bridge. Bridges take on the colour of the team that built them, but are otherwise identical. Units will only attack a bridge if ordered to do so, and enemy units fully controlled by AI will never attack a bridge. Brdges block the movement of water-based special units.
