If you’re not familiar with Noclip (the website, not the documentaries), I have a treat for you. Coded and maintained by creator “Jasper”, Noclip.website contains versions of game levels that you can fly around in 3D to take a closer peek at. The site features a heck of a lot of Nintendo games (and some Dark Souls), but Jasper has also shared a bit of toying with Half-Life 2‘s levels. They’ve recently stitched together (almost) all of HL2’s levels to do a bit of a flythrough showing off how they look all lined up in space together. Surprisingly decent, it turns out.
