Sectors
Player progression in Unnamed Space Idle is mainly governed by conquering Sectors, since they unlock new mechanics and features. Each sector has specific set of enemies that will spawn in it and sector boss. In order to clear the sector player needs to defeat the sector boss.
Early sectors are small and can be completed fast, but later ones will take longer to get to the boss. Getting additional engine speed will help so speed up going through the sectors after the Prestige.
Clearing sectors will reward players with different Unlocks that will help to push faster and further next time.
If player wants to push as far as possible it's important to properly counter enemies in each sector. Getting the right Core equipment and build will help to clear sectors way earlies. Sector Push Builds will help you to get the right set of equipment to progress faster.
