Trophy description - Clear the mountain pass without alerting the enemy (Mission 1)

Trophy - Bronze

This trophy can only be obtained in Mission 1 - Siege of Tobruk. After taking out the first few enemies and blowing up the truck you will have to proceed through a mountain region and take out four enemy artillery (or Nebelwerfers). During this entire section of the mission you cannot get spotted by an enemy. The coloured ring above the enemies head can turn yellow but it cannot turn fully red as that indicates that the enemy has spotted you.

The easiest way to do this is to play the mission on Cadet difficulty as the enemies are less likely to see or hear you. Make sure you crouch by pressing Circle and only take enemies out with either your Welrod or a stealth takedown from behind (press triangle). If at any point you are spotted you will have to reload your last checkpoint. As such it is advisable that you make a manual save after each kill as to reduce the amount of backtracking required if you are spotted.
