I really dig it! Its feel like a Ultimate Doom take of TNT, but its not at that level either.
Its a great adventure mapset, leaning more to the atmospheric and realistic architecture.
First and second episodes are amazing. Introducing the new enemies as the maps unfold.
But midway around episode three it start to lose steam, with a serie of really short maps and then maps really similar to the originals, this is not bad at all, just feels a little uninspireds.
Fourth episode on the other hand, feels extremely rushed, with a lot of monotexturing and undetailed areas. Its not bad, but coming as the ending episode it could be much better, specially with the degree of detailing the author showed on the precious episodes.
All the episodes offers a good challenge, even on Hurt Me Plenty, but don't expect anything near the difficulty of NEIS.
All in all, being one of the few complete Ultimate Doom megawads, its pretty good and i liked the new enemies sprites and the music used, almost all the time.
No, this is not good by any stretch. First 25 levels feel like they are all the same - colorless, flat, dull and bland. Next 3 look like deathmatch arenas with a handful of monsters. Again, all pretty much the same. The last two are pitch black mazes - oh what fun. As for the secret levels - I abandoned both. Map31 is a maze alternating between pitch darkness and flashing primary colours and map 32 is simply an incomprehensible mess. Possibly acceptable if you just want to kill some time with mindless point and shoot, but not what I would call an enjoyable Doom experience. At least it avoids degenerating into slaughter.
I rarely quit a wad in disgust, but this one did it. It was pushing a 5 star experience, but then the slaughter stupid started ~map19 and only got worse. It's not clever, not amusing and absolutely not entertaining. It ruined an otherwise good wad and left a very sour taste. Why do mappers do this? Played on HNTR and it really was that bad.
