There is no denying that Last Shelter Survival is a complicated game with plenty of in-depth progression and development options to consider as you progress. What makes this game particularly difficult to get to grips with is the lack of instructions and information on how these in-game features actually function.
In-Game Help
Next to the Base building there is an in-game help option in the form of a GuideBoard sign (see above). If you tap it you will open two otions, one for 'Help' and the other other for 'Service'. The 'Help' option is a collection of text based help files about various aspects of the game and will answer some basic questions. If you can't find the answer to your question there you can always try the 'Service' option where you can ask specific questions and contact the game developers with any problems you are experiencing.
Internet
The game developers also have a Facebook page and a website which you can use to contact them through if you are encountering problems with the game.
Alliance
If you are part of an alliance the quickest way to get answers is to ask in the Alliance chat feed where you will probably find helpful people who have been having the same problems as you and will only be too pleased to help you.
SuperCheats
If you are not part of an alliance you can always ask your questions on SuperCheats where other visitors may have the answers to your questions.
