Here you are, freshly landed on Mars by the FIRME's shuttle which company make you sign your contract.
A bunker and some materials has been given to you (sadly the most basic one).
We are going to visit it together.
The kitchen
Like all flat you have to supply food from time to time: buy some ration (with an empty stomach it is hard to dig efficiently)
The Coffee Booster is a supplement that you should drink before each exit: it doubles your digging capacity for the first hour.
Be careful if your exit last less than 30minutes (emergency return or space suit damage who force your to make small exit), the coffee booster has no effect!
Toilet :
You have to clean them regularly(Martian bacteria are dreadful and you risk the explosion of your toilet). Use the anti-bacteria spray if needed
