Mission 8: Project Nova Intels
Intel Location #19: You will find this Intel on a table with a lantern and files in the 2-story building you come across just about halfway through the mission. There will be 2 snowplows outside of the entrance.

Intel Location #20: You will find this Intel on a table next to a cabinet in the hangar with a rocket in it. The table is in a room in the back right corner. You will need to pass through this hangar to continue on with the mission.

Intel Location #21: You will find this Intel on a pallet that is almost completely covered in snow at the end of the ship. It will be right before the stairs to the right. Make sure to grab this before you use the rope to get off of the ship and before time runs out.
