I’m having trouble obtaining my Survival Expert trophy while playing on Grounded

**Potential Spoilers**
With how the Grounded difficulty is structured, some upgrades & skills are altered or removed in order to balance gameplay. This means that you may not be able to obtain the Survival Expert trophy because Listen Mode upgrades are fully removed on Grounded. If you do prioritize these upgrades while on a lower difficulty before or after a Grounded run, you can get the trophy. But, if you miss them, fully upgrading the alternative skill trees on Grounded will not award you the trophy. To be safe, we recommend doing trophy runs on lower difficulties to ensure all base skills have been upgraded.
