Cover the subway with castles (the subway is there so as not to spoil the drawing of the upper map), and place a teleport near each one, as Monsieur Shnurov would say. The types of castles are fixed. At the top is the starting zone, where the teleports randomly explode when the map is initialized. Let's say 6 castles – that's one spawn point, another 6 – another spawn point, and so on, until there is enough space on the map.
