− | In some maps, particularly during Events, conditions might be required to further progress the map. A map may be split in distinct phases, with each phase requiring a different set of objectives to be met. These objects range between successfully defeting enemy fleets, defending against enemy Air Raids, attaining air superiority on certain nodes, beating previous bosses, and so on. As soon these conditions are met, the map advances to the next phase; new nodes and/or paths will be unlocked, older paths might become inaccessible, and older routes might change severely. | + | In some maps, particularly during Events, conditions might be required to further progress the map.
