Lost Planet: Extreme Condition Target Mark Location Guide
In my quest to obtain all of the Target Marks I found myself visiting various websites. After a while, this process became tedious, hence the birth of this guide. The saying is that necessity is the father of invention holds true once again.
I have personally verified the accuracy of each Target Mark in Easy, Normal, Hard, and Extreme difficulty.
You should be able to get the TMs on each mission on the first pass except for some missions on Extreme. Replaying missions is simple - just select Mission Select from the main menu then chose the level and difficulty. Additionally, you can pick up only those you are missing and skip the others you've picked you in previous replays. To view which TMs you have, go to the main menu and scroll down to Records and select Campaign.
If you have any difficulty with any of the Target Marks, please post your question in the Lost Planet forum on Xbox.com. I hope this helps you as it did me. Good luck fellow gamers and may the Force be with you as you will surely need it to beat the game on all difficulties and collect the Target Marks.
