Hints

• You need to build beds in a bedroom to get people into your bunker.
• Hold SPACE while in a room to produce resources manually. (You DON'T need employees assigned to the room to do this.)
• Air raids will start after a few minutes.
• During air raids your employees won't produce anything and some might die of fear.
• You will lose all resources in your inventory if you are on the surface during an air raid.
• The air raids will become more frequent and last longer over time.

The game doesn't track achievements, so it's up to you to award them to yourself. ;)

• Don't let anyone suffocate, die of thirst or die of hunger.
• Never lose any resources by being outside during an air raid.
