The Bunker is a game about John, the last remaining survivor in a decommissioned government nuclear bunker in an alternative world version of Britain where nuclear war broke out in the mid-80s. He was born on 3rd July 1986, the day of the disaster, and 30 years later he is the only one left of the 59 people who were once inside. He has never seen the outside world, but has food supplies for more than 27 more years. Every day he follows a strict routine his mother has learned him: take the vitamins, check the radiation levels with the dosimeter, listen to the radio for activity, do a radiation check, eat and check on the remaining food, and finally he reads to his deceased mother, still lying covered in bed. That has gone well until day 11,111 when the server crashes and he needs a procedure to restore it. It causes him to break his routines and venture into the long forgotten areas of the bunker. There are also many flashbacks that reveal what took place previously.
The game consists almost entirely of live action full motion video shot on location at a real nuclear bunker along with a few static stills, complemented with a soundtrack. The video has no computer generated effects, CGI or motion capture. Sometimes small decisions are presented, such as choosing what to read, selecting an activity, turning a knob, reading a document and so on. The player controls a cursor and certain parts of the environment offer interactivity through hotspots. While the game is entirely linear and there are a few moments where a bad or late decision is "rewound", there is mostly no risk or time pressure aside from a small amount of Quick Time Events. When these are missed the scene needs to be replayed. Some small, optional elements are available, such as locating toys, locating computers, and reading documents.
