Head to the right of the exit with tall grass and crawl inside the log. Then after the GRU fight, in the room Sokolov was first found in and then during Operation Snake Eater, inside the warehouse after the battle with Pain near some boxes. The motion sensor will display animals as white dots upon use, just be wary of nearby enemies when doing so.

Very Easy

Very Easy is an option if you just care about the achievement. This difficulty will automatically grant you the EZ Tranquiliser gun to make the challenge slightly easier.

Time Paradox

Failure and deaths will reset the challenge back to the previous checkpoint, be sure to recatch anything in that area if this happens.

Gotta Eat 'Em All

This challenge doesn't require you to eat each item however doing so will make a note of it in the CURE menu. Use this to help keep track or use Steam Overlays Notes feature.

Multiple Ranks

The rank shown on the ending results screen doesn't have to be Markhor in order to complete this achievement. As long as you met the requirements, it should unlock as usual.

Item Full?

Be sure to have room to pick up the food/item to ensure you don't accidentally miss anything. Injuring yourself on purpose to make room for medicine or eat up some previously caught food if necessary.

This guide is a combination of multiple guides I have compiled onto Steam for both ease of access and preservation. The reason I created this guide was due to the source I have used the most only being obtainable through a Wayback Machine archive. Because of this, I can only take credit for simply putting this together on Steam and providing some of my own writeups and screenshots. I will link the archive below as that is the only way I know how to credit original author of images used in this guide.

This is also my first guide, so I apologise for any formatting errors and/or lack of presentation. Hopefully, I can return to this later with some updates. If there are any changes or suggestions to the guide, feel free to let me know.

I hope all of this helps,

Good Luck!
