This is kind of misworded. You only need to collect the picks and data crystals for this achievement. The picks are black and have pictures of a skull on them. You will find 1 per level in the levels marked on the story screen. Every level with them has 2 picks, and 2 Data Crystals. If you DO NOT see 0/2 picks or 0/2 crystals on the story level selection for that level then there is none in that level. They are all out in the open and I got most of these just button mashing. YOU CAN get these one easy difficulty.
