Primordium Day Zero — is an adventure sci-fi action game with a first-person view, and also a survival simulator, with a bias in construction, the collection of information and resources, and interaction with the outside world. The events of the game take place in the distant future, in which people have long left their home planet and set off to conquer and colonize new worlds. Well, in this future you will become the commander of the Nexus Defense Forces, a special organization that fights for humanity and its survival with rebels and other threats. You have to go on a trip, learn a lot about the world in which you find yourself, survive, and do much more.

Day Zero Build, Craft, Survive — under the screen is an extraordinary network, huge and poorly researched. But, there is something dark lurking in the depths of the web. Welcome to Okulus, the virtual world is meant to act as a way to eliminate the threat. Will you survive? It is your duty to gather information, strengthen the defense of the Nexus, coordinate strike teams, and fight any rebel forces that may arise. Be prepared to build your team and fight for peace in Nehus. Unfortunately, there were those who considered the destruction of the moon unnecessary. Political parties and religious groups began to form, and the Marian Empire was split with threats of secession and civil war. In an effort to keep the peace, the Nexus Defense Force was created. You just received the rank of Commander of the Nexus Defense Forces.
