The GBA version of Wolfenstein 3D is a defilement of a great PC game.
The game looks just like the original, only lower-res, with the menu fonts cut down for the smaller screen. Surprisingly, the status bar is translated quite well. However, the dim GBA screen is disastrous for a game like Wolfenstein, making it difficult to see enemies and objects, especially while being fired upon.
The sound effects are straight from the game, although slightly tinnier due to the inferior GBA sound hardware. All the familiar gunshots, treasure pickup sounds, and pidgin German screams are reproduced faithfully. Unfortunately, the music was cut out completely. That is a great shame, because the music was one of the best aspects of the PC original and work through the same system as the pickup sounds, so there's no excuse to leave it out.
Gameplay is where the GBA version of Wolfenstein falls on its face. The basic mechanics are the same as ever, but the execution is terrible. The framerate is very choppy, despite the primitive engine, and the controls are very loose compared to the PC version, making aiming difficult. In large open areas, the framerate is so bad that the player is effectively rendered a siting duck, netting the GBA verrsion a "hard" rating despite the easiness of the original. Frantically spinning around a room while Nazis shoot at you from several directions is a maddening experience.
As with the original, there is no multiplayer. Period. The original 60 levels are all there is to this game, and once you've completed them, there's nothing more to see. This further damages the replay value of the game, making it uninteresting after the first time through the game, if the slack controls and abysmal framerate don't drive you away before then.
The GBA version of Wolfenstein 3D is a defilement of a great PC game, a total disappointment, especially to a Wolfenstein fan like me. If you want to play Wolfenstein, get the original and use VDMSound to fix the sounds. This GBA port is frustrating, flawed, and just not worth your time.
