Classic Maps

Classic Maps are unlockable maps and campaign based on classic Doom and Doom II levels found by discovering retro secret areas in the main campaign of Doom (2016).

They are discovered by finding a hidden lever in each level, that opens a secret door, and then entering the 16-bit texture mapped area hidden behind the opened door.
