when it says the video covers the, entire game, does mean everything in the game + the bonus bits as well

When a video is described as covering the "entire game," it typically means that it includes a comprehensive walkthrough of the main storyline and all major gameplay elements. This can also extend to side quests, collectibles, and significant in-game content. However, whether it includes "bonus bits" such as Easter eggs, hidden content, or DLC (downloadable content) can vary depending on the video. It's a good idea to check the video's description or comments for specifics about what is included.
