You are an American tourist in London, strolling through Kensington Gardens, when World War III begins and the city is vaporized moments after the story starts. Survival seems impossible unless you enter another time, another place, or another dimension.

Escaping London is only the beginning. You are drawn into an exotic world filled with giant fly traps, strange creatures, and other dangers, where time and space follow their own intricate and mischievous logic.

As you explore fantastic places and collect curious objects, you try to discover the pattern behind the events. If you succeed, you will reach the New Mexico desert minutes before the first atomic explosion, code-named Trinity.
