Hey guys. I remade the entire first level of Duke Nukem 3D in Minecraft, check it out!
I'd recommend downloading it and exploring yourself so you can see all of the secrets I threw in. Every secret from the game is there, plus some more easter eggs and hidden things. Also, when you get to the end part, break the glass and jump into the lava. When you respawn you'll be inside a little credits room I made explaining how long it took me to make and what not.
