Also can anyone share their strategy for sneaking? I keep losing myself and starting over from the beginning
I'm assuming this is sneaking before being found. The strategy is to utilise the directional audio to continue moving while crouched and put distance between you and the enemy. DO NOT RUN. You can walk sometimes if there is enough distance between you.
If the enemy hears your footsteps (much louder when running and slightly quieter when walking) he will investigate that area. Sometimes hiding in corners or somewhat hidden areas work.
