Oblivion Remastered stays so true to the iconic RPG that it even includes a secret door, allowing you to finish the game in under 15 minutes
Players are finding more iconic tricks from the original in Oblivion Remastered, making the game much easier to play. One fan took advantage of the legendary door for the game's story finale and finished it a few moments after the prologue.

the original (released in 2006), including the developers' blunders. In this way, in the new iteration, legendary doors appeared, which lead... straight to the finale. Thanks to them, the YouTuber nicknamed Bacon_ managed to complete Oblivion Remastered in 12 minutes and 30 seconds.
I am using an Orc because of the Berserk greater power that has Fortify Fatigue. I cast it then use all my stamina and let the power run out while sitting on a chair making me ragdoll because my stamina is in the negatives, while ragdolling I go ham on the scrollwheel which places the camera way above your head and lets you clip your camera into walls. I use that to access the Temple of the One door doing the skip [to the game's plot finale] - we read in the video description.
The YouTuber's strategy allowed him to move to an alternative version of the temple district in the Imperial City, where we find out how the game ends. He accomplished this feat shortly after finishing the prologue, while skipping the entire main plot.
The hidden doors in TES IV: Oblivion were probably left there on purpose by the devs, who also didn't remove many other shortcuts, tricks, and bugs (although some of them were slightly modified). They include, among other things, the option to duplicate most of the available items, which requires just a bit of fun with our inventory screens and an external chest (via Eurogamer). In the remastered version of Oblivion, the devs didn't forget about the iconic line spoken by the character Tandilwe. During a conversation, you can hear the voice actress saying the same sentence twice, asking for a retake in between.
As you can see, sometimes even mistakes can become an iconic element of the game. Fans' comments also confirm this, as they really appreciate the creators for keeping them in the new edition.
