Just spotted over at Doomworld, that 20 Years of Doom has been released. It is a collection of 9 medium-sized Boom-compatible maps made by members of the French Doom Community to celebrate our favorite game's 20th birthday. The project's goal was the following: Each map in this set is to be composed of various elements inspired by 3 consecutive maps from the classic Doom IWad and arranged in a new fashion, allowing you to revisit Knee-Deep in the Dead, The Shores of Hell and Inferno in a condensed yet revamped way. The wad includes many new twists though, and the overall difficulty has been raised a fair bit so that modern players could still enjoy the gameplay. Cooperative / -solo-net mode is also implemented.
