13. Borderlands 2's Hidden Minecraft Room
https://www.youtube.com/watch?v=1xI4deYmDNQ Somehow the Borderlands franchise has never managed to take off and soar quite as highly as the likes of
Halo or Call of Duty, but it hasn't stopped developer Gearbox putting in just as much effort into every subsequent iteration. Point being, the B2's
very well hidden Minecraft tribute room, whereby you'll have to journey through a number of different locations in sequence after Chapter 9 just to get the appropriate wall, before breaking through and exploring. When you do finally arrive it's easily one of the coolest pieces of content to pay tribute to the legendary now-billionaire Markus 'Notch' Persson, responsible for the game's meteoric rise to cultural domination from 2009 onwards. Inside you'll fight a string of Creepers, before an aptly-named 'Badass Creeper' pops up as a mini-boss - and be warned; these guys pose quite a challenge, so make sure you're specced up accordingly before delving in.
