Sectors & Waves

Sectors are sets of enemy waves. Sectors ending in any number other than '0' or '5' is a normal sector and will contain 15 waves of Enemies. Sectors ending in '0' or '5' are boss sectors and only consist of 1 wave of enemies containing a Boss. Waves contain 10 enemies if they are in a normal Sector or 4 enemies and a boss if they are in a Boss sector. Locked Cargo is earned by completing Sector 80 and every 10 Sectors (any Sector ending in a '0') after 80.
