Lost Planet 3

Story related, cannot be missed.

You will be in Pickett's Folly for this. Using the winch on your rig, zipline over to the debris in the lava. Fight off the Akrid along the debris, there are only Sepia and Bolsepia here so it shouldn't be a problem at all. Now hook over to a cavern area which can be accessed by turning left as you continue along the debris. This is where the medicine is located. In this area you will have to fight a Targaant for the first time. Make sure to tag it using your DNA tagger bullets, this is not the only chance you have to tag this Akrid but you may as well get it out of the way. Aim for the exposed orange section of the Tangaant's tail to take it out as quick as possible. After this fight, you will return to the Camp of the forgotten where you will have to kill an Emmlid Akrid. Even though this is not the only time you will encounter this Akrid, make sure to tag the DNA of this enemy to get it out of the way. Also, ensure that you tag 1 of the flying enemies that the Emmlid releases periodically as 1 of these need to be tagged for the Geneticist trophy. Once you kill the Emmlid, the trophy will pop as you have returned the Medicine to the Snow Pirates.
