Trinity — An Interactive Fantasy — The player character spends the last day of their holiday in Kensington Gardens in London. The likelihood of a successful return flight to the United States is decreasing by the minute due to a number of unusual reasons. Hordes of nannies have blocked all exits from the Gardens, and the grass actively resists attempts to pass through it. Worst of all, a glimmer of light on the horizon soon announces the appearance of a Soviet missile with a nuclear warhead. As the rocket approaches, time begins to slow down, and after solving small logic problems, the player character finds a strange door hanging in the air. The door leads to God knows where, but this place is in any case more attractive than the epicenter of an atomic explosion.
