Adventures have set borders, and nothing will generate outside of them. Items and blocks won't leave the boundaries of the Adventure, but mobs can.You won't be able to walk over blocks, or go underground. You can walk around in the real world and explore the Adventure, but this is strictly horizontal. You have the freedom to move around within the Adventure, with limits.

Once it's placed down, you're free to explore the area as much as you want. This is where your well-lit, open space comes into play. Once you load up the adventure, you'll need to select a location to place it. Stone is the minimum I'd recommend (if all you have is wood, it might be best to avoid Adventures for a little longer,) but iron will ensure you won't miss out on even the most valuable of loot. If you need to conserve space, make sure you at least bring a sword and a pickaxe. Make sure you have a variety of tools in good condition, as well as some food to heal up if you need to. These are the items and tools you can bring with you on the Adventure. When you first open an Adventure to play it, you'll see your hot bar down at the bottom.

No armor or shields in Minecraft Earth means a fight can very quickly turn deadly. Most things you can get with your hands if you're okay with taking longer, but you need to at least have a pickaxe for harder resources. Various tools like axes, shovels, and pickaxes all work similarly to vanilla Minecraft, so they might be useful to have around. You need to at least have one sword in your inventory, preferably of stone quality or higher. Adventures can lead to you running into hostile mobs like zombies, and also mean you'll need to collect resources using various tools. Once you know where to play, there's a few things you'll want to do to make sure you're prepared.

Even the Adventures generated from Adventure Crystals only stick around for a maximum of ten minutes, so only spawn it when you're ready. GPS tracking, high brightness, camera usage, and just running a game, in general, all lead to an empty battery. Just like Pokemon Go, Minecraft Earth can be quite the drain on your phone's battery. I recommend playing outside, if you have a yard or nearby park, as long as you're mindful of other people. If you're playing indoors, be mindful of furniture and other obstacles. Adventures may have you move around quite a bit, so you'll want to have some space to play in. Darker play spaces may lead to Minecraft Earth not being able to track the Adventure properly, and it could slide all over the place, or not show up at all. Daytime is best, but if you're playing at night make sure your environment is very well-lit.
