[2022] how i can get map of the grounds?

To clarify, are you asking where you can find map items? If so, you can find Charts at campgrounds, and GPSes at military locations.

Some curated maps (e.g., Arid) will always provide a chart view. Additionally, playing on the Easy difficulty will also always provide a chart view. You can also configure custom difficulty settings that provide you with a chart view and/or satellite view.

For single-player, you can configure your difficulty settings from the same menu you select the map you want to join.

For multiplayer, you can filter for servers based on difficulty.
