You know, I saw this on ModDB and said to myself, is this really necessary? I can just go play Wolfenstien.
1. It is free
2. It has better music
3. More and better sound effects from other Wolfenstein games (including "Return to Castle Wolfenstein") and from me ("New High Score" message)
4. Better graphics technology including curved walls, reflective floors, etc.
5. Proper 3D enemies and objects rather than 8 views that are pixelated up close.
6. 3D bosses rather than always seeing the front view
7. The "WolfPack" Wolf3D Pacman level that lets you get the power pellets and eat the ghosts.
8. Has a partly finished original level which does a few things that are impossible in the original game
9. Has dismemberment where you can shoot or knife off people's head, limbs and finally cut up the torso

11. You can set people on fire with the flamethrower or blow them to pieces with the bazooka
