A SECOND BEFORE US is an adventure game that takes place on a planet after a global catastrophe. The shown future is a dystopia in which the human race is practically wiped off the face of the Earth, and the surviving survivors are obliged to huddle on the territory of the Delta complex.
The last people call themselves colonists. They have no names, the memory is subject to the erasure procedure after a certain time, and the only task they are called upon to perform is to collect memories of the life of generations before the disaster. The past is restored by immersing the colonist in a realistic simulation where the desired events unfold. The researcher only needs to follow the correct order of actions and find important fragments in order for the memory to be collected.
Colonist #183, the protagonist of the game, suddenly begins to ask irrelevant questions about the true purpose of the Delta complex, about his work and the lives of his comrades - and now it depends on the player's choice whether the usual way of life will continue or whether the fate of all mankind will be irreversibly changed.
In addition to the futuristic locations of the complex itself, the player will have to visit completely different territories: the search for answers will lead him to an ancient lighthouse, a wooden settlement, and even an Egyptian temple.
