I only recommend this game if you're a big fan of Doom and want to experience what the predecessor was like. Otherwise, it's quite outdated. It's fun and interesting at first, but 60 levels is way too much (that's one more than Doom and Doom 2 combined!), there is just not enough variation to keep you interested for that long. I personally got exhausted around halfway through, but I pushed through it. At least the final episode has a treat in the form of an ultra-difficult secret level. I recommend using the ECWolf source port for its improved quality-of-life, it automatically detects your Wolfenstein 3D installation on steam.

A piece of gaming history, I can see how people found this impressive when it came out but in today's times this game just sucks. The controls are clunky and confusing, the graphics are god awful and the game is just generally incredibly boring.
While this is a mediocre game, you have to appreciate the importance of this game and what it did for the entire industry.

Simple fun. This was one of the first games my family had on our family PC when I was a kid. My mom was super anti-violence (no Mortal Kombat for us), so I think my dad got this on floppy disc from someone at work or maybe my older brother got it from a friend because my mom definitely wouldn't have let us play it if she knew lol.

The first three episodes are classics and are definitely worth playing to experience the humble beginnings of id Software and see what is essentially the prototype for Doom. Plus it never gets old to shoot Nazis and take down Hitler. The next three episodes are kind of a mixed bag. They aren't much more challenging (I would say the lack of mutants makes then easier than the original trilogy of episodes), but they get kind of tedious by making you run around the map and collect keys, sometimes from hidden passages. Episode 6 kind of does away with that and is mostly straightforward, just with tighter corridors. None of the additional boss fights do anything special compared to the fight against Hitler, but there was only so much they could do back then (and I'm not sure John Romero and John Carmack even worked on the expansion episodes).

Definitely recommend playing through ECWolf, which is super simple to set up, and gives you more modern FPS controls (in the original you had to hold ALT to strafe, which feels strange now IMO) along with automap to make finding your way through some of the labyrinthine levels less of a pain. I never played Spear of Destiny as a kid, nor the challenge mission packs, so I'll probably try those next, but I originally got those seperately before Bethesda bundled them with Wolfenstein 3D, so I'll review those missions on the old Spear of Destiny Steam page later on.

If you like classic FPS games, recommended to experience the granddaddy of them all.
