Doom II fills in the gaps that The Ultimate Doom left wide open, and securely fits in the gap of a masterpiece.
The soundtrack by Robert Prince, The Ultimate Doom, was a modified version of the original SNES soundtrack. There is also one of these for Doom II, the music once again brilliantly composed, and set to make a good atmosphere within the game.
It's long, kind of repetetive, but very long. It has the same qualities of Doom, but it doesn't quite have the spark that it deserves from its predecessor.
It is still fun, and it's also added on more monsters, more scenery, and more textures, so all the WAD creators can make fresh new material, with a new, refined look of the original Doom.
By the end, you should feel accomplished, it's a long, and very hard journey, obstacles such as the new monsters, the army of hell has grown in this game.
