The Town is one of the main Location, after climbing the hill leaving the Foothills. There's a few different things you'll need to find in order to move on to the Research Complex. You'll need the 2 different parts of the Lab Security Code, and also interact with another astronaut, who is potentially one of your crewmates. In Town, there's also an oxygen tank which you'll need to replenish your own o2 reserves after a brief interaction with the astronaut. Also, you'll need to be careful with the dust devil (which contact with will result in instant death), which blocks your access to the Red Brick Building. Once you gather the two portions of the code, you can head to the left of the town to the Research Complex, passing by the Cemetery.
