10 Secret Levels In Iconic Video Games You Totally Missed

9. Wolfenstein: The New Order - Unlock The Original Wolfenstein 3D

Machinegames' little underrated shooting gem is still one of the finest head-blasters you can find on current hardware, and despite the team not having the gargantuan budget of something like Destiny, it didn't stop them packing all sorts of secrets and easter eggs into the experience for fans of the franchise to dig up. For this one, you'll have to forgo talking to the team about the next mission as the game gives control back to you following a string of early missions, and instead, journey upstairs to locate BJ Blazcowicz' 'bedroom'. Here there'll be a prompt that simply says 'Nightmare!' Prodding this will boot up an emulated version of the original Wolfenstein, as the team take a page from Hideo Kojima's MGS 4 book of tricks, showcasing just how far the series has come through consecutive comparisons between the oldest and newest iterations. In this rework of the old mode you'll still have the modern sense of movement and animations, but enemies and the world around you are incredibly primitive and brilliantly pixellated in their emulated form. Let's have more of this in future games please, it's ace.
