Version reviewed: Beta 6 patch 5 on 02/25/2022

Pandemonium Classic: Unity Edition is a great game if you are looking for a sandbox transformation game. I say this because most of the games on this site are either you transform people or people/monsters transform you but this game gives you the option to choose what type of monster you are and transform people or you can have have a whole house of monsters come and try to change you while you try to escape using one of the three methods. There are multiple settings that you can use that gives you a set of monsters or you can select them yourself. I find it to be the perfect scenerio creating game because of all the settings to customize everything to your needs.

Now onto the part that I have small problems with. I found that with the diplomacy setting I have yet to have it change the behavior of any of the humans or monsters. I tried everything to see if setting different monsters from hating humans to being neutral or allied with humans would work and none of it has. Another thing is that the difficulty scale between the three escape options to be unbalenced. I understand having a easy medium and hard one but I find that the key and stone escape methods are way too easy compared to the portal one.

One last thing before giving the final part of my review. As most people can tell from finding this game after finding the official game first or just reading the creators message this game is based on the House of Pandemonium Remastered game. Now although it is supposed to be played as one of the protagonists of that game I would enjoy a little more characters or even in the future if the creator made a game similar that had a bit more of a wider range of playable characters or even more monsters/transformations that weren't all based on a monster (even though there are some that aren't).

Most of the cons are just personal little things but I felt like putting it out there. All of that said I would still consider this game to be nearly perfect with the only thing that brings it down are some incomplete settings or ideas that are yet to come and when they do I will update this review but for now I would say the game is an 8.5/10.

Probably one of the greatest games on this site. That's a big claim but it does something no one else does, does it well and does a whole lot of it. (Full disclosure: I helped in a pretty big way enable this game to be made. The character creator program needed mods found, I found a lot of them.)


Pandmeonium classic is a survival arena game where a group of girls find themselves in a manor and have to try and escape before they get TFed by the monsters that show up. It's basically an FPS where you run around the mansion trying to find weapons and ways to escape before the monsters TF you. The game doesn't end when you get TFed, you just play as a monster trying to TF the other humans. Except for the other Pandemonium games nobody else does this. There are 80+ kinds of monsters each with their own TF sequence and style of gameplay as them.  Also in it's favor is that you can modify just about every setting in the game which lets you make your own sandbox of fun.

Art and design:

The art's functional, but more importantly expressive and does an excellent job of conveying what the monsters are like. It's all 2d sprites made in 3DCG. The mansion is pretty barebones, but it's obvious the focus is on being easy to understand over being pretty.

Gameplay: An FPS sort of thing but with a focus on melee. It does the job, but isn't exceptional. The problem that keeps it from being great is that the melee isn't much fun. NPCs move erratically and turn so quickly that actually catching one to hit can be a challenge sometimes. They added range weapons so if you can't get the melee down you can still defend yourself. I'm not sure what they could do differently to fix melee though, I doubt they have the budget to make a TF dark souls. Every monster has it's own gameplay gimmick which is impressive, although balancing is an ongoing progress. Perhaps most importantly ways to win were added so you have a goal to work towards. A lot of the gameplay is enjoying losing is fun until you figure out the systems on offer.

TF content: Great! There is a lot of TF in a lot of varieties hitting on a lot of popular themes. Each monster has it's own flavor but every monster has a volunteer variation which is a nice touch. Also has four seperate insect girls, bee, ant, mantis and moth. One thing to watch out for is that there is almost no sex in this game. If you want sex and TF this isn't the right game.

Conclusion: I really recommend at least trying this game, it's something no one else is doing. If you like monster-girl TF and the related corruption and mental changes it's a must try. If you just want a lot of TF sequence it's also good to pick up.

I've been really enjoying the development of this game, and at this point as a sandbox I'd say it's definitely surpassed those that came before it.  The unique behaviors of the different types of enemies is excellent, and the gameplay itself is pretty easy to balance to what you want.  I did want to provide a few points of feedback, as per A5P5: 

  • When an enemy type is not in the game (0 spawn rate,) it would be nice if its special map object didn't appear either (except for the slot machine because you can pick up chips.)  I'd like to try doing one or two enemy types on a cramped map, but when the map gets small you wind up having rooms crammed full of giant harpy nests and golem tubes and the like that just block your vision and don't do anything.
  • Left hand weapons (firearms, throwables, etc.) should probably be considered their own category when rolling for items, which then rolls again to see which you get.  I'd like to use them in the game, but they bloat the item table so much that you never see any potions or other items.
  • The trap spawn rate seems low, even when set quite high.  I very rarely see dark clouds even when the spawn rate for that trap is set to maximum.  A setting for trap odds in boxes would be awesome.
  • Adding human spawns makes the game just last forever in my experience so far...and having a bunch of renamed girls with the same appearances showing up is just...strange.  I'm sure there have been plenty of suggestions to add characters (male, other races, or just to see new looks) but as the roster of monsters grows, I'm sure that becomes more and more daunting of a task to consider.  I'm honestly not sure where I was going with this one.
  • Keep up the great work!

I've been following this game since the first version, since I was a fan of the original. At first I dismissed it as a clunky, broken, and unnecessary remake. A lot of time and updates later though, this game has turned into something pretty great. The gameplay still feels awkward, but the sheer number of transformations and options make this one of the most enjoyable and replayable games on the site. 

Kudos to the developer and everyone who helped with the 3d models, for providing regular updates and constantly improving the game.
