Minikit #1: These minikit requires you to destroy the skeletons of five explorers. The first can be found if you turn around at the start of the level.
The second skeleton can be found next to this movable boulder.
Skeleton number three is tucked behind the tent when you reach the campsite.
The fourth skeleton is hanging out on this ledge just after you cross the tightrope with Legolas.
The fifth and final explorer skeleton can be found just after the segment where boulders fall from above. Head through the hatch to emerge on a lower ledge where the explorer’s body lies.
Minikit #2: If a few skeletons weren’t enough for you, you’ll have to raise four flags to get this minikit. The first sits on a ledge just after you cross the second snow pile.
Head left from the rope that lowers into the campsite to find the second flag.
During the segment where rocks fall from above, hang right to find the third flag out on a ledge.
After crossing the narrow ledge with wind gusts, you’ll find the final flag on the next ledge.
Minikit #3: Very close the fourth explorer skeleton you’ll find a cracked tile. Use Gimli’s axe to shatter it, revealing parts to a snowman. Use the build action to put him together, and use Legolas to shoot the target on his chest to gain a minikit.
Minikit #4: Just past the third flag you’ll find a cave clogged with Mithril boulders. Use the Berserker’s bombs to destroy them, revealing a minikit.
Minikit #5: Past the Mithril-clogged cave is a ledge you can reach via Sam’s rope. Climb up and use the Uruk-hai to open the glowing handle chest for a minikit.
