Calling it revolutionary is an understatement in every sense. This near perfect port does the original Wolf 3D justice.
I'll get right to the point regarding the inconsistencies. First off, the music is considerably slower paced. It's still intact, but how slow it is in comparison to the original is all too noticeable. Second, medkits have a slightly different sprite. It's exactly the same, except for the red cross on the top, which is now a heart. I wouldn't go so far as to say this is censorship, but I wouldn't know what else to call it; all the other graphics in the game remain the same. It's just a very bizarre and unexplainable change. Lastly, you can't hold the "use" button down while running along a wall to open secrets. Not a huge deal, but it means in order to search a wall you have to keep pressing the "use" button (A on the Xbox 360) on every section of it. Doing this while pushing the control stick to keep moving is troublesome, and it's easy to end up missing the secret wall you're trying to locate because of this.
Wolfenstein 3D doesn't have a story so much as it has a name for your protagonist and an explanation for why you're killing Nazis. You play as the allied OSA's finest agent, B.J. Blaskowitz, and you begin the first episode of the game escaping from Nazi imprisonment. The game has six episodes, each with nine normal levels and one secret level, making for a total of sixty levels. You have no objectives, other than to reach the exit of each level and kill a boss at the end of the episode, fending off Nazis and finding secrets filled to the brim with treasure along the way. You have four weapons at your disposal, all of which besides your useless knife using the same bullet ammo: a pistol, a machine gun, and the maniacal grin-inducing chain gun that eats ammo like popcorn. There's only six types of enemies to use these weapons against, as well as the six different bosses (or seven if you'd count a repeat of one of the bosses). The Nazi-hoarded treasure you find only serves to give you more points, but now those points have a purpose if you're into this kinda thing: online leaderboards. You also have lives, but they're just as completely useless as they always have been, because you can save and load at any point in time. Dieing means losing your weapons, ammo, and progress on the level, so I don't see why anyone would ever let themselves die and respawn, unless they're trying to challenge themselves.
This port of Wolf 3D is exactly the same as the port of Doom, as it's made by the same developer, Nerve. The similarities include the lack of widescreen support (however, I prefer it that way, as it preserves the original gameplay), the fancied up main menu interface to make the game more presentable in today's market for old-school games, and the online leaderboards. They don't end there, though, but the next two things on this list really disappoint me to no end. I still can't get used to the controls. At least in this Wolf 3D you don't ever have to worry about not having number keys to switch to specific weapons like you do in Doom, but even with the ease of strafing and sensitive movement, that movement sensitivity is exactly what throws me off. With a keyboard you're moving at full speed all the time, and most likely looking with the precision of a mouse, but even looking with the keyboard still feels more natural than control sticks in these old first-person-shooters. It controls great, really, but it's the getting used to it part that I personally can't grasp. The other negative similarity in the Wolf 3D and Doom ports is the poor as Hell achievements. I was hoping for creative and challenging achievements like killing a boss with the knife (actually, on reflection, that sounds utterly impossible), or finding the "Call Apogee, say Aardwolf" secret in that fiendish maze, but all you get are typical achievements for completing each episode, and six others for doing other criminally simple tasks like complete a level, find a secret, etc.
In all honesty, there isn't much else of importance that I can say about Wolfenstein 3D. It's $5 for many hours of the oldest of old-school first-person-shooter gaming. To those not familiar with it, the gameplay is as simple and repetitive as it gets, but you can't hate on Wolf 3D for what it's done for the gaming industry. The leaderboards are there for those who want to show off their Wolf 3D skills and how well they remember everything about the game, but beyond that, it's just the never ending two-dimensional maze that is Wolf 3D all over again. The score I give this is not meant to reflect this antique and legendary game itself, because critiquing an old game re-released like this against modern standards goes against my nature, but more the value of buying it on the XBLA or PSN. It certainly won't have the same appeal to modern gamers that it would to the veterans, but there's reason enough to compel anyone with any interest in playing Wolf 3D to buy it. Need another reason? You get to kill Mecha-Hitler. If that doesn't immediately make you go out and buy this timeless classic, then I doubt anything will.
