Amazing !
Never seen anything like this.
I can't believe this is one BSP file !
And what a lot of detail !
A beautiful map with great gameplay that feels like a campaign (I mean, more than 1 map ...)
This is an absolute "must play", I think.

Basically like 3 related levels. Each layout is good and challenging, third one is insane difficulty. One complaint, exits caught me by total surprise first two rounds. 9+ ratubg

Sorry, ratubg=rating. Should've proofread.

when i try to play this i get the following message: Hunk_Alloc: failed on 3828464 bytes.

Any help?

Use Fitzquake085, Bengt Jardrup's enhanced Glquake, or Darkplaces.

ah it works now, thanks for your help :)

What a fantastic map! Upon completing the first part in 20 minutes on nightmare, I thought the loading time the map required was strange, but quickly discovered the reason. Great fun, not easy but not masochistically difficult either, and the attention to details and eyecandy were also plentiful. Recommended!

I just replayed it with the DirectQ engine (deserved propaganda ;))and it also works fine with that.

Sheer purrrrfection! And that's understating it a bit as well ;)

If you still play Quake then as Ron stated: "this is an absolute must play". And indeed it is.

Great idea, great execution! It's like a mini-episode in itself. I had a hard time during the last battle until I've found the spot where the shamblers couldn't get to me. And all the time during that battle I saw the secret with the shaft in plain view that I couldn't get into.

A novel idea, certainly. It starts off very impressively, with an unorthodox reverse intro, followed by a Doom 2 reference that made me feel all warm and fuzzy inside (surely I am not the only one to notice that?).

After that there is plenty of almost excessive, headache-inducing detail everywhere – which unfortunately, in combination with somewhat non-linear gameplay, makes it very easy to get lost, especially in the initial incarnation of the map. The second and third run are very clearly set in the same place. Yes, there are some changes, but I was hoping for a bit more differentiation. I was hoping for it to feel like a bit more like a mini-episode of three maps, rather than one long map that could have benefited form a bit more visual variety.

Luckily the second run is noticeably shorter and more violent and so does play noticeably differently, whereas the third run ramps up the difficulty even further with a more treacherous environment in addition to a mass onslaught of monsters (medieval monsters really do not belong in an environment like this, though). So there is a definite sense of progression and rising tension. The final battle is particularly brutal – but inventively so and ultimately winnable, with a bit of strategic thinking and perhaps a few attempts.

One of the more unique maps out there. I am pretty sure it force changes to skill 3 upon loading the third "version". Definitely a risky concept but I think it works for the most part.

Bizarrely, it seems I've never played this before. More fool me. A most enjoyable base blast, really not far short of three separate levels. If anything, I might have liked to see the three runs resemble each other more closely.

I love it that Digs is not content simply to make excellent maps, but is constrantly striving to make maps that are both excellent and innovative!

Can't believe I never rated this insane clusterfuck map. Digs singlehandedly elevated himself to one of my favorite mappers with this single release.

After Virtual World, another original map by Digs that I should love, but actually not quite so.

The premise is interesting but I dislike having to cycle through 3 different difficulties: it makes the first part much too easy and the last part very annoying - there's a reason why I never play nightmare and it's not cool to force it on me!

The map's architecture is nice but then again, is very confusing, which isn't helped by it changing quite a lot between each iteration.

Also, there's much too many spawns in the last section.

Finally, I encountered what I can only qualify as a bug in the middle part: there was an invincible spawn that I couldn't hurt no matter how hard I tried.

Oh, also:

In the remake of the e2m1 cage, I could only press 2 of the 4 buttons because I couldn't figure out how to extend the other 2 walkways. And I had to finish the last battle in god mode.

It is brilliant how Digs used some mapping magic to create a mini-episode in one BSP. By slightly altering the layout of his large Base complex, he created new experiences in 3 different levels. It was equally clever how he adjusted the difficulty between levels to add intensity to the progression. The final battle is insane; however, after several tries & some strategy, I was able to pull through. Unique, well built, & fun, I agree that it's excellent ...just save before the final battle :)

Very interesting map - or rather, a set of maps. Very old school, bearing some distinct 'Doom 2' influence. "The Parallel Worlds" may appear rather shallow at the very first glance, but once it becomes intelligible regarding what the clockwork behind the realm in process, is - things start to become more thrilling. The map circulation, reiterates on the same or roughly similar place - as if entering different, parallel timelines, not too distinct from one another - exploring various aspects of the place; each stage becoming also more difficult and arguably more complex. The final stage, is truly brutal in terms of difficulty balance, very old school in the way of player/protagonist treatment. I did not have the perseverance to finish the third stage, seeking keys in a rather non-linear environments - a mark of time, spoiled people me - but it is cool concept; even if some players could argue it also nears going cheap with reiterating, rather than making new. I would say though that a good reiteration could be as interesting - if not more interesting, proper background given - than an entirely new design altogether.
