No Illusions

Prologue is the first level in Tomb Raider: Underworld. It is known for featuring the largest skip in the game: Prologue Skip. The skip was first found shortly after the game was released. Usually, players would drop down from a ledge where a cutscene would play, however, this skip allows the player to avoid this cutscene and jump to the section which is normally reached at Croft Manor. By finishing the rest of the platforming in the level, Lara reaches the cutscenes which lead to Southern Mexico. This skips the levels: Mediterranean Sea, Coastal Thailand, and parts of Croft Manor. In speedruns, it skips approximately 15 minutes of gameplay.
