Earth Must Die is a story of inflated ego and the thirst for total revenge, presented in the format of a satirical adventure. The narrative centers on Vvalak Lizardtongue, ruler of the Tyrithian Empire. After his domain fell to the onslaught of Terran invaders, the despotic monarch resolves to take revenge on all of humanity. His sole goal is the complete destruction of planet Earth. On this mission, the protagonist is accompanied by the flying robot Milky, who supplies his master with milk.

The project called Lair of the clockwork God is handled by Size Five studio, which is remembered by many already released games, for example, Swindle, decorated in the style of fantasy grotesque and Ben There, as well as Time Gentlemen, Please. The developers said that the creation of the video took a very long time, as they tried to show as many game moments as possible, while not giving out any secrets from the game or plot twists so as not to spoil the surprise. Apocalypse and two idiots who survive in it. One of them does not know how to bounce, and the second is stupid and can not understand puzzles and puzzles. This is what makes the game exciting and in a sense unique.
