Mars Miner 2: Deep Mine Rescue & Reclaim is an iOS game that lets you explore six planets, each with its own unique terrain, plants, animals, and minerals. You can also interact with them and even destroy some to get to the artifacts that are hidden within.

You will need to gather the resources that are hidden in the planet, including iron, coal, gold, silver, and gems. The game will provide you with the tools to do this, such as a pick, a shovel, a magnet, a pan, a pot, a stove, a furnace, a smelting machine, and a variety of other things.

Once you have collected all of the resources, it is time to start the extraction process. This is when you will need to use the tools to get the coal, gold, silver, and gems out of the planet.
