For this achievement you need to complete the campaign in Inhuman difficulty, this can be very difficult unless you use stealth to your advantage. Here are some helpful tips for Inhuman difficulty:

• Take cover! This is vital if you wish to survive because the enemies are extremely strong and will kill you in no time.
• Try to avoid using your knife against dinosaurs as it is far more difficult and will often result in you getting killed.
• Watch out for grenades as the enemies will very rarely miss you.
• Watch out for stationary turrets because they will kill you in an instant.
• Try to keep a long range weapon on you at all times because killing enemies from a distance if far easier than trying to shoot them up close.

Good luck and if you manage to complete the game on Inhuman difficulty, Congratulations!
