To me, this is yet other E1 style full-episode, it's plays good, not too bad, just like the original E1 but getting lost so easily. And unless you're doing Pistol-start or your ammo will be TOO MUCH, well, it's not author's fault as id did the same shit on the original E1 too, but on 2013 it may just a little awkward.
Most of levels just plays like typical E1 levels, nothing too special but for those who like the E1 should like this too, unless "getting lost/multi-ways" is not something you like...for me, I just do "sv_fastweapons 1" after E1M9 beaten, shame on me, I know, but that's why E1 style just too easily to fall into a boring monsters-killing-fest if nothing so special, and until E1M8, I didn't see any of them so special...maybe some secrets...:\
Overall, I would say it's fine E1 episode replacement, for those who love this kind of levels.
Old map from 95. Not really intresting design, but I didn't find any wrong alignments homs or whatever. Monster placment is ok. Except one room cramped with trees and mass of hitscanners without any cover. Progression is very confusing, you may find some unintended shortcuts which confuses even more.
Akimbo weapons are nothing new but it is nice to see the Doom weapon line-up to be duel-wielded. Maps that are tight on ammo can be a problem and the secondary fire modes are rather underwhelming, with some being straight-up worse than if you shoot normally. Otherwise, it's a fun mod.
Classic style, plays so id feel, good and bad designs too, since it was designed for the DTWID project and then rejected. Impossible to get 100% kills because a monster cannot get teleport out with 1-time only teleport line...
If you like the old-school id style, this one is for you, if you're not, well, maybe give it a try if you don't really hate id levels.
The maze part is killing me. With Doom's 3D capabilities building a maze is something one might try to show to friends or try out for oneself, but not release as a map for the public!
Because the maze does not work. And it is not AS difficult, just very tedious.
And it is a pity, because there are several very cool areas in the map. The area with white platforms is very nice, although it definitely needs more lighting. Everything is way too dark.
Anyway, a very uneven map, with a lot of corridors and several cool rooms. All in all, a fail as a map, a worthy specimen to look at for some design inspiration.
