oOo: Ascension (UP)

The Delta Sector is the 4th set of levels you’ll play. They open up after you've completed all 10 levels in the Gamma Sector. There are 10 levels in total you need to complete and they can be done in any order. It's highly recommended you go for the Triple-O scores as you go to save yourself a lot of clean-up after you complete the game. The times you need to strive for are as follows:

4-1: 00:09:50
4-2: 00:08:00
4-3: 00:14:00
4-4: 00:18:00
4-5: 00:15:00
4-6: 00:23:00
4-7: 00:14:00
4-8: 00:13:00
4-9: 00:14:80
4-10: 00:18:00

If you're having any trouble with any of the levels, please see oOo Mastery for a full video Guide showing all 90 levels being completed with their respective Triple-O times.
