Again, an improvement over the last one (castle3.wad). Still some hallway-isms but this time they aren't a thousand miles long. Also, repeating the same "puzzle" more than once is never a great idea. But, it's quite playable and actually a little challenging in some spots. 2.6/5
A slight improvement over the quality of castle1.wad (I didn't play castle2 because it's already been reviewed.) The starting actually looks sorta cool, giving you a sense that this map might be better than the previous ones. But, it's only marginally better, with outrageously long hallways as the main annoyance. Combat exists but is still super easy, especially if you use the myriad artifacts in supply. The worst part was getting to the end of a massive hallway and finding out that I needed a green key, which would have been about two minutes of backtracking if I didn't use the turbo cheat. 2/5 would skip
Other than a few competent moments, this is quite passable... as in, pass it by to play a more exciting map. At best it's incredibly easy even on high difficulty levels, with pretty basic and usually ugly architecture, and at worst you get to navigate through a maze of single-linedef walls which of course don't block your shots. If there were anything other than melee golems around, it would have been even more annoying.
No, this is not a 5 star wad, not by a longshot. It is an acceptable time killer though and it's also marred by some teleporter confusion. It's small and the cyberdemon is pretty easy to get rid of, so as name suggests, don't panic.
