A pretty intricate and fun to explore map sets in a semi-realistic castle with lots of secret passages, doomcute "realistic" furniture that even include a library made out of sector art stuff. The fact that this is a Retextured Doom map is shown greatly here. Pretty neat map, the only real breaker is that this map have a unused red skull key and other keys for the locked doors (blue and yellow keys)? At least i didn't find them. I had to noclip trough them for complete the map. If it could not be for this bug, it will be a great map. But overall, is pretty good. The baroque music is fabulous. Make me think of women in dress and huge wigs dancing in the marble throne room! Or demons in this case.
An old mid-1990s map, based around a large main arena which contains some interesting structures. For a while it's tough going, and you may die a handful of times (as I did), before getting the hang of the layout and formulating a strategy. Once you get the yellow key though, and access to the BFG, it should be game over for the baddies.
Your calculations can be thrown off track however if the Archvile decides to emerge from the movie theatre at an early stage, and take a stroll out in the open. Another thing to watch for is the Cyberdemon entering the said building while you're in one of the auditoriums, and blocking your escape. I experienced both of these events, with fatal consequences...
This is not a night sky, it's a space sky, with highly visible galaxies. It won't make sense on Earth because you can't see galaxies with the naked eye, but shall work in space and on any astronomical bodies without or with thin atmosphere.
Also there's a problem with the permission sections in the text files. The outer text file, published with the archive, says:
which gives you limited permission to use the sky in your maps, but still not permissive enough to let you adapt the graphics to any modern rendering.
However, the internal (from the archive) text file says:
which, while suspicious of lack of attention on writer's part, on this current state it means that you just can't use these graphics in your mods. You can try to contact the author to get a permission, so there's that chance.
So which one is it? Because without further clarification, "yes AND no = no".
This is fairly straightforward, and most players should be able to complete it on UV in not much more than about 15 minutes. That's not to say it's a pushover - ammo is fairly tight for a good part of the map, and you could fall foul of some distant chaingunners if you're unlucky.
It's a sky texture replacement wad, it has several files for each iwad and pwad like Eternal Doom. It's a bit dated these days, but for true old-school feel it should be enough. If you feel tired of default sky textures in your iwad playthrough, load this and enjoy different view and feel.
