Scavenge everything and analyze it
Just like the first game, you want to collect all the materials you can grab in Grounded 2. Pick up items such as pebbles, sap, and clover leaves, and then analyze them to learn new crafting recipes. The tutorial will introduce you to the game’s resource analyzer, which is a machine that lets you analyze resources you’ll find out in the wild.
You want to keep analyzing materials throughout the entire game. Resource analyzers are found at each Ranger Outpost on the map.
Your first main mission objective is to find your first Ranger Outpost, so head to this location as soon as possible and start scanning your materials with the resource analyzer inside. Each Ranger Outpost will have an analyzer, so these are pretty well spread across the map.
The analyzer has a limited battery and has to recharge after you’ve scanned four items, so there is a cooldown period, but you can always just visit a different outpost if you get impatient.
Here we have a full guide for finding and using all the Ranger Outposts in Grounded 2.
