Caves and Mining

About
CAVES are found occasionally on Mars, and are used to collect resources.

It is not possible to enter one without a special SUIT.

Clean CAVES
Some caves have clean air. However, it is still necessary for a MINING SUIT of any kind to be in the player's inventory to enter one.

Dusty CAVE
The cave at the Dusty Mine Entrance cannot be entered without the player having a DUST SUIT or QUEST DUST SUIT. This is due to the dust inside the cave, which causes the miner standing near it to request that the player pick up a DUST SUIT from the "COAT MERCHANT."
