The Boy Achievement in Aery - Vikings
Finish the 2nd Level
How to unlock The BoyYou can access this level by completing the previous level or by selecting ‘The Boy’ from the main menu.
There are 28 crystals to collect in this level. A counter appears at the bottom-right corner of the screen after you collect the first crystal. Most of them are visible and out in the open but since there is no map, if you are having trouble locating any, refer to the video in The End (90G) (timestamps have been provided in the YouTube comments section).
Note: In this level, the crystals are almost black, making them difficult to see against the color of the background, so look for the yellowish-green glittering effect to help you identify them.
