The video discusses the storyline of the Doom video game series. The series is divided into two timelines: the classics (Doom 1-3) and the reboot (Doom 2016).
In the classic timeline, the story begins with a marine who is sent to Mars on a mission but is instead tasked with killing innocent civilians. He refuses and is sent to prison. Later, he finds himself on Mars again, where he must fight against demons that have been unleashed through a portal to Hell.
The marine's adventures take him to various locations, including Mars, Jupiter, and Hell, as he battles against the demons and their leader, the Icon of Sin. Along the way, he discovers that the demons are being summoned by a powerful being known as the Queen of the Demons.
The video also discusses the storyline of Doom 3, which is set on Mars and follows a different protagonist as he battles against demons that have been unleashed through a portal.
The video concludes by mentioning that there was a planned sequel to Doom 3, but it was canceled. Instead, a new game, Doom 2016, was released, which is a reboot of the series. The video host invites viewers to request that they tell the story of Doom 2016 in a future video.
