Wolfenstein 3D is one of the most famous FPS games in history, and a milestone on the way to the modern 3D video games. You play as William “B.J.” Blazkowicz, an Allied special forces spy, who performs dangerous mission on the enemy ground. His main task in Wolfenstein 3D is infiltrating Hollehammer Castle, where the Nazi scientists, led by Doctor Schabbs, are working on a secret project on creating invincible super-soldiers. According to the intelligence reports, the research may involve raising the dead, but since it sounds highly improbable, it needs to be checked first.
The game has been divided into 6 episodes, which can be played out of order. Apart from the official main “Eisenfaust” campaign, Blazkowicz has to take care of other assignments—starting with the most important, which is breaking out of prison, the eponymous Castle Wolfenstein. You fight using four weapons: a knife (which is actually only useful against dogs) and three kinds of guns, all of them using the same kind of ammo. You face a multitude of foes, mostly regular foot soldiers. At the end of every episode, you fight a boss enemy, who is more resilient than the other opponents. However, the bosses are not quite difficult to defeat if you remember to dodge.
All the levels in the game are labyrinth-like, which make it only too easy to get lost (sadly, the protagonist doesn't have a map of any kind). Som doors can only be opened with special keys, which come in gold and silver variants. Every stage ends with you finding a lift and taking it down to the next level. Fans of exploration can try finding many hidden rooms, which can be discovered by knocking on walls. The rooms are usually full of treasure (worth extra points) or ammo, and can also contain the most powerful of the guns.
The 3D engine of Wolfenstein 3D for PC / Windows may seem archaic now, but at the time of the game's release, it was a complete novelty. The title's biggest downside is its monotony, resulting mostly from the lack of varied or refined architecture. All the walls are made of identical square blocks, only with different textures. There are no stairs of lifts (besides the end-level lifts, of course)—every stage consists of just one floor. Despite all of that, however, Wolfenstein 3D is a very playable production. Many a PC owner in the 1990s became a fan of exterminating Nazis in this once-revolutionary game.
