So...this release comes with a Mission 10 that appears to be pointless (it's just the same as the normal arena for unlocking, but without any guns so you can't hit any targets). Also what's the deal with Mission 7? You spawn in a room adjacent to another room that has two locked doors, the third one leading to a dead end.
Reading the changelog, it quickly becomes apparent there's some weird thigns they are considering to be changes. New loading screen system and new weapon upgrade system, followed by "new graphics and sounds for the new <loading screen and weapon upgrade screen>"
There's also stuff like behind-the-scenes info "+New+ Door Mechanism: Can require more than one key to be used / puzzle to be completed / switch to be turned on / etc." <<this just means "hey, we can do things differently, but haven't done so."
As for bugs: aside from the mission specific ones I mentioned above, there are many. Their new "function that controls everything related to changing from one level to another" causes the character model to load in carrying the weapons she doesn't currently have (updates when you open inventory). It also saves your last HP value for the HUD until you get hit (correctly uses the real value instead of the old one). You can aim down sights while staying in the idle animation. Often times enemies ignore damage (I mean no damage taken or knockbacks or blood splatter at all). This invulnerability appears to be whenever they are in or for a while after exiting certain animations. Toggling between windowed, borderless, and exclusive fullscreen causes the fps cap to change to 30. Master volume controller does not control any volume settings. Zombies interacting with doors plays a global sound effect. The directional lighting in a lot of maps is very bad. The global illumination doesn't bake any objects (only terrain features), which looks jarring a lot of the time. The camera is absolutely abysmal at all times, and often times glitches out. Clothing tends to cause a lot of clipping. Models tend to clip into each other, too. Breaking free of a grab can throw enemies out of bounds.
Other (non-bug) issues: it is poorly optimized, as when running 30fps at 1440 on a 2080 super, the main menu uses 50% of the GPU (not just GPU memory utilization, but actual processing). It also uses more GPU and CPU when tabbed out, compared to when in focus for some unknown reason. Despite this, the textures are very low quality and usually appear stretched or shrunken. There is no audio balance between various SFX. Controls aren't great, and the camera sensitivity settings do nothing when playing with a mouse. Why can't we zoom in/out a bit while in control of the player like we can for the sex animations? Knife is indeed useless, despite the loading screen trying to say it's somewhat useful - just kick them and then curb stomp. They die. Knife takes ~25+ stabs to the face to do the same. The damage system as a whole is rather unbalanced anyway, as you're just repeatedly shooting the head until you get a crit; non-crit damage is useless. Why can't we navigate menus using the mouse? They can very easily use PhysX or something similar to capture the cursor for when it is hovering over icons. Why do some levels have the changelog sitting as an interactable object? Specifically in places that are prone to the player being attacked? Why is the loading screen system there in the first place, if it's not giving real tips? Most of it is just the FAQ about patreon and stuff. Why do we get double loads? You select a mission, see loading screen, press a button to exit loading screen, press the continue button, loading screen repeats, exit loading screen, then you are finally in a mission. The way the missions are made is that they are simply test levels for new things they were working on, so there's really not much in the way of good level design going on (hell a lot of them are actually demo levels in the asset packs they're using). Most maps have no sense of direction or meaning behind objective placement, and there's nothing that leads players the right way. The way they modified the models is very jarring - they simply added giant floppy dicks on everything that really look weird (seriously, they look like flabby pool noodles that go all the way to their knees). The way they try to apply "stretching" physics around insertions looks very bad. The entire perineum region of the character, including the crotch, vagina, and anus are all clearly out of place, with some things protruding and looking "stretched" from the body. The inflation mechanic does the same. The mesh lines for the character model are clearly visible. The sound effects during sex do not match the animations in the slightest. The sex mechanics as a whole seem like they don't really belong from the grabbing with the terrible camera angles and cheesy animation, to the "struggling" both during the grab and sex. The way the sex works is you press f once to get out, or wait for a bit and press f once to have it do a cumshot before ending (which quickly zooms into the location of insertion, but keeps the current camera angle). You are able to rotate and zoom the camera in sex scenes, but not pan, so sometimes you are forever unable to see the character's face. The cum is rainbow colored for some reason? The enemy AI is just "see player? Run to player's current location" but doesn't update the player position as it is moving (so will just run to where you were 2 seconds ago). The detection is also very weird, as some enemies seem to know where you are without seeing you, and others ignore you unless you are right in front of them for a solid 5 seconds. If you're too close to normal zombies, they straight up never attack the player.
Showcasing a lot of the visual issues, including the floor texture:

All in all? The raw game itself seems to have barely been changed since 3 years ago. Sure, there's been new levels added (a few of which are unplayable) and small visual additions...but the actual user experience remains the exact same, and it is very rough to play. The gameplay being mostly unchanged, in addition to the sexual aspects being *entirely* unchanged in so long really makes me question what the devs are doing with their time and the money from the patreons. They went the "gaming as a service" route for how people are allowed access to the game, so they really should be making visible progress, which they clearly are not doing so.
