Problems occur when you have a full inventory and you want to take stuff from the tubes. There is no way to drop items, so you will have to find an empty locker or use up a health syringe to offload unnecessary items, thus making space. I found this system to be extremely tedious. What would have been a lot better would be to have an additional sidepack which could store things away. You really are on your own in Martian Gothic, as the brief history of the base and the garbled distress call is the sum of your knowledge of the situation.
Help is at hand though.
In some rooms around the base you will find computer terminals. These have a variety of functions. I won't spoil it for you. One of the main terminal functions is to enable you to save your current game position. It's within this game that you can save your position.
