That moment when the map starts and you simply feel amazed and astounded with the ambiance, breathing in the atmosphere, without the will nor courage to move, anticipating the experience, if you finally let it - it becomes known: this is it.
I can perfectly see how and why this map could possibly trigger some people. Yes, “The Forgotten Sepulcher” is a lot; it is also dense in content - but nobody says you have to take all or nothing from it. Just take some. Maybe you will return sometime, try a different route perhaps. If not, even a little experience of the map, should give you fair example of what the whole picture is about. No need to be obsessive. Do yourself a favor and simply let it have secrets; no need to know them all. If you feel like, go ahead, try discover them all, talk about the map, involve in communities - it would be great. If you are satisfied with just a little, then good for you; move on to another realm, find something more attune with your taste. There is plenty to search through.
In my opinion, truly an act of artistry “The Forgotten Sepulcher” is; far beyond mere craftsmanship. It does feel like surpassing ‘Quake’ not by a step, but by two - definitely too much in order to avoid possible controversy.
The environmental storytelling in “The Forgotten Sepulcher”, does tell of a mayhemed place - a place of grand battle, waged once in a distant past. Notwithstanding, the danger, is very much undead - or alive - like an unstable, slumbering structure, ready to bury alive anyone who dares disturb it. The ancient foes haunt the inert battlefield, taking captive of every soul daring to cross their paths of deathly quiet. It is a dungeon full of traps.
“The Forgotten Sepulcher”, is not only an advancement in the way of gameplay approach within the universe of ‘Quake’, but also is it a technological breakthrough, proudly making great use of the “Arcane Dimensions” base of assets and technology. I say it superficially, though, myself being not the most significant authority to give an opinion in this regard. But I can see how the modern way of the map, differs from the original game (1996) or the original-flavour gameplay formula. ‘Quake’, has come a long way and who knows what we are yet to see in the times to come - hopefully speaking.
What else to say, if not: this is the new ‘Quake’ - and I am for it.
