There are two types of collectibles that can be found within the Awakening DLC.Classified Intel:
These are randomly picked up from searchable items, and their locations change during every playthrough. You will need to pick up a total of 3 of these intel types to unlock them. Only 1 player can pick it up, and it will automatically unlock the intel in order. Each area will contain between 1-2 intel items, and this can easily be boosted solo using the first area and then dying during the first drill section.Encrypted:
These are also permanent laptops that can be found on the map, and their locations are as follows:
1. Fugitive - Area 1 - There is a small cave like room accessible on the mountain face to the right of the entrance to this area. Use platforms, or the mushroom to reach this area.
2. Defector - Area 2 - Again, another small cave to the right of the entrance to the area. Use jumps to access it, or go around back to walk in this area.
3. Executioner - Final Room - Upon reaching the final room, jump up on the ledge on either side of the entrance, then jump from there onto the higher ledge above the doorway to find this last piece of intel.
There is also an Epilogue intel that is attained by completing the DLC, but it is not required for the achievement.
