I don't know if anybody has made this yet, or if anybody really cares.
Well.....anyways, this game is pretty decent. I do like how it sticks to the original "run and gun" combat and the no reloading. Most of the weapons return, such as the BFG and the super-shotgun. A bunch of original enemies like mancubis and imps appear, though the Imps have a different appearance than the original.
Gameplay is really intense, and you have to keep on your toes to dodge thousands of projectiles and enemies, and health is usually only gained by killing enemies. They now added "Glory Kills", which are extra gorey kills which can be used when enemies are staggered.
Campaign is pretty good, the plot is O.K, and the bosses are edgy.
Well, if anybody wants to share their experience, feel free to comment!
