Here's a breakdown:
Mission: The Ministry of Magic
* Objective: Infiltrate the Ministry of Magic and retrieve a prophecy about Lord Voldemort.
* Location: The Ministry of Magic, specifically the Department of Mysteries.
* Enemies: Death Eaters, including Bellatrix Lestrange and Lucius Malfoy.
* Gameplay: This mission features a challenging fight in a large, open environment. You'll face various Death Eaters, use cover, and utilize different spells and potions to progress.
* Clock Tower: The Clock Tower is a prominent feature of the Ministry of Magic, and you'll fight Death Eaters near it as you navigate through the building.
To clarify, you don't sabotage the Clock Tower in the game. You fight near it during a mission to rescue a prophecy.
It's possible that you might be confusing the game's storyline with the events from the *Harry Potter and the Order of the Phoenix* book. In the book, a group of Death Eaters, including Bellatrix Lestrange, attacked the Ministry of Magic, causing significant damage, and they specifically destroyed the Clock Tower during their escape. However, this event isn't recreated exactly in the game.
