Curiosity can lead to amazing discoveries or gruesome death. When exploring, keep a few things in mind.
Be Prepared, Be Ready
Before you head out, repair your armor if necessary, as well as any weapons or tools you plan to take.
Always keep water and food available. Carry or load up extra on your dino for extended trips. Monitor your basic needs on the HUD and don't let them fall below 45% or your specified threshold.
Keep an eye on the temperature so you don't dehydrate or become hypothermic.
Have backup weapons and tools available, in case of breakdown and you are unable to repair them.
Pay attention to your location, as you can quickly stumble upon a dangerous area with much higher level dinos, or a large group of lower level.
