Hell has broken loose once again! As before, you're the only one who can send the demons back to where they belong. Face 16 challenging levels, divided into 4 distinct episodes with custom monsters, weapons, textures, music and heavy action! Using GZDoom, you can expect a large amount of features that were never possible with the original game like slopes, scripts, fog, 3D-floors and many more things that will significantly alter the experience you had with the vanilla version of Doom II.
