TLDR - Play the original game instead it's half decent game and this was only meant as a quick cashgrab with almost nothing worth playing it for.
Well if you liked the original then... good for you, because I certainly did as well. But this game was never meant to be a proper game, it's at best 5$ horse armor, the new additions were mostly already implemented in the original game, they just required supporter access. So let's judge this game based off it's sole unique factor then, the scenario. ZOMBIES, who doesn't love them right, in an 18+ game we know where this is going. Our poor hapless school guard gets bit trying to help some girls and... grows a penis? Understandable she wants out of this predicament and the nurse tells her to nab zombie girls, and thus our game begins proper. It's basically the same game with a twist, you can become female or futa, now why would you ever want to go female you may ask? Well you see, you're forced to, many times throughout the story mostly to fuck men, that's right MEN. Certainly they existed in a pretty shoddy way in the original game, and then later made a toggle because it turns out not many people liked their existence, but now they're front and center baby. Over the course of the game you learn about superzombies, who are apparently causing this mess so you need to find and lock them up, problem is they stole your nurse. much fucking later you get her back and then are told to go to the next town and... do this all over again. Once you've managed to club the 2 superzomibes in this location, after a very long and confusing section of the game your reward is, to run into the prison for no reason at all. Yep it's fucking padding time, the prison segment has no bearing to the actual plot so once you finish it up you're now ready to CURE the virus. Do the bossfight and end the game and you're done.
So that scenario sucks, it's full of a lot of wasted time doing meaningless bullshit and since it's a zombie game you spend most of the time fighting. But it's a zombie game so there has to be survival crafting right, it's kinda part and parcel with the genre, but sadly no. In fact zombies drop money, an infinite amount and you don't need a lot to buy the consumables you do need to survive so you'll have plenty for the HOT customization. Afterall you're a chick the original had a great paperdoll system, all that money is going to be used on yourself like a real gir- and no. The outfit system is the exact same as the original for the protagonist, preset with no customization otherwise, well you can bleach your hair blond and tan your skin but that's it. Which is especially egregious since that paperdoll system where you collected clothes for your jail girls, was gutted from the system entirely, now undressed clothes just stop existing and you can't collect them. So why does it matter if your a chick with a dick now, you can't even use the unique aspect of it and all it really did was sometimes add a pair of breasts to sex scenes? Well you can turn into a girl silly, or rather you're FORCED to. Many sidequests and of course those story bits requires you to lose the dick and get fucked, and I don't think that's what most people signed up for when they wanted to play this game, regardless the tone disgusts me. The original was pretty scummy but it felt like a Saturday morning cartoon kind of scum, in this one you're collecting woman to be raped by a porn director, or stealing woman to be raped by prisoners.
So honestly I can't recommend this game to either new players or ones who have played the original. I haven't even talked about this developers scummy always online DRM bullshit, but I'll save us all the rant this time. Go play the original preferably with male toggle off it's a pretty solid 3/5, but this, honestly I'd rather give it a 1.7/5 it's not good. Make sure you grab the mods for both to get the uncensored+ supporter items, although probably grab those items after you finish the story. Hopefully their next GAME will be better then this, but honestly I got no hope for that, guy made one decent game and that's probably all he's got, have fun while you can I guess.
