This is just an early version of Plutonia Map09.
There aren't many noticeable differences up until the final area which is just a simple room with an exit you can walk into right away.
The Plutonia map, Abattoire, isn't among its strongest maps, but the final room is one of the most memorable fights in the set. This version doesn't have it, so it lacks the best part of the final version.
Not really worth playing if you've already played Plutonia. Something something historic value...
Seej is another early slaughtermap from Dario Casali. With roughly 1000 monsters, it surpasses both Punisher and Go 2 It.
Unlike Punisher, Seej manages to keep up its pace. The more open layout and better monster combinations make infighting much less viable and there aren't many safe spots. The item placement is also much more thought out, you actually have to explore the level to find weapons. Powerups and health are also more scarce.
The only time the level slows down is once you clean up most of the 300+ initial monsters, but then you start progressing trough it and Seej pulls its greatest trick. Schutzstaffel!
If you are familiar with Dario's Requiem Map23, you'll immediately know what this means.
The ghost monster setup is really similar to Requiem, they even both come out from some sort of Blood Fountain.
I'm a big fan of using ghost monsters, and they are very effective here. From then, until the very end, Seej never lets down.
The level isn't very nice to look at, since 90% of it is the same brown brick texture, even though the architecture is pretty nice. Although, once you start killing, all the corpses laying around add a lot of colour to the map :)
Overall, Seej is worth playing both as a fun slaughtermap and for its historical value.
Punisher is pretty much Dario Casali's version of Go 2 It.
From the start, the map seems to have more 2 it. The monster count is three times higher, you start getting attacked right away and there seem to be Pain Elementals everywhere. The problem is, once you gain a footing, the levels becomes much easier than Go 2 It. Monster Placement here is very haphazard, meaning that even with fever power-ups, you shouldn't have a problem. This also results in lot of infighting and not the good kind. Most of the population just kill each other even before you get 2 them. Punisher has one last trick up its sleeve though, and that is releasing a load of archviles once you progress far enough, which thankfully makes the map much more challenging again.
Overall, it's a good early slaughtermap. I think it looks better than Go 2 It, but the gameplay in its middle gets too easy, as the monster placement isn't as good as Go 2 It. Then again, it was built in 2 hours.
Punisher is still entertaining and worth playing if you like Go 2 It and want to see Dario's take on the concept.
Also, it has not new music so I suggest throwing some custom midi at it. 20 minutes of D_RUNNIN can't be good for your health.
