Imagine some fear and hunger type shit having to deal with injuries from letting the eggs hatch in her like the tentacles rip up her cervix and womb while they quickly try to exit her pussy and you have to heal it quickly and have a temporary walking or crawling only debuff cause she’s sore
That yeah and at the higher levels of difficulty eggs hatching could result in death. Imagine chestburster from Alien, the pregnancy would be longer so you would have more chance to act, but you would HAVE TO do something about it instead of just not caring as we do now. You fuck around too long, you die. Worst case scenario, you would have to do C-section like in that shitty AvP movie (but since there are already medical stations and robots in the game you would just have to make your way to a closed operating unit, pay lots of money and then disappear for like 10-20 seconds lol).
Until labor starts and cervix dilates, the womb is sealed, so the tentacles wouldn't really have anyhere else to go but have to force their way through the softest tissue, abdominal wall. Besides WHAT is on the other end of those tents? Are they just snakes or is the actual creature like an octopus with a big body on which the tentacle is attached?
As for rape trauma, I remember one mod from Skyrim would incapacitate your character if raped too much, she would randomly start crying and collapse to the ground, curling up in a ball.
The mods I hated the most are the ones that would just give stats debuff - that's such a fucking lazy way of doing anything. Especially when the game's vanilla engine itself already was capable of so much more - the reputation system allowed for not being able to enter towns if your rep was too bad, inhabitants not willing to talk to you or even attacking you, being accosted by guards and thrown out the gate, etc. Off the top of my head, only one mod out of dozens used that mechanic and that was the Skooma junkie mod; other mods that could've used it, where you could be hated and persecuted for being a slut or having sex with non-humans didn't even bother trying. Of course that's not useful in DZ, but I just had to rant a bit lol.
In DZ there are many possibilities for trauma effects - the ones you mentioned, plus stuff like shaky hands that would make it harder to aim until you calmed down, overlay stuff (kinda like the sperm over the screen), health loss if raped too many times (trauma to vaginal walls due to lack of lubrication), bleeding... With new health system you can also include pelvic injuries or fractures from being fucked too hard, etc. One thing that would make it difficult however are the map designs, there is hardly places to hide for a bit to heal - where the hell would you hide on Streets or even Swamps? The AI are practically everywhere.
The problem is, the new primary needs and injury system already fuck the player over enough. It's hard to stay alive without getting sex and injuries involved and at higher difficulties I suspect we are already being overwhelmed with that alone. Traders are too few, essentials are difficult too acquire (especially the water drops in boxes scattered around the world are almost non-existent, so you are forced to buy from traders), foods and drinks are too weak (+40 eur for SIP of water that only recovers like 20%, are you fucking kidding me?!), effects don't last long enough, stats drop WAAAAY too fast...
Then include OP omniscient AI that will one-shot you across the map through 5 different forests and the game passes the "not fun anymore" and heads directly into the "fuck this, I'm deleting this PoS" territory.
Honestly, this game needs not only toggles to turn injury and food system on and off, but also sliders so we could adjust shit on our own. One of the reasons I hate Unreal engine is that it prevents users from modding it easily.
The point of all this is to force you to play carefully and advance tactically. You would be forced to consider each puddle, whether it's worth risking getting caught by tentacles and risk pregnancy; whether you REALLY want to take those Hawker jobs to have sex with AI... IRL, would you REALLY want to wade into water or swamp and get violated by an alien? Can you be absolutely certain they won't kill you instead? Or would you rather first kill them all first and only then try crossing the water? Plus this way there would finally be a point and sense to contraception pills, cum expulsion, etc. As it is right now I don't even bother trying to prevent pregnancy anymore, cause I know it's just a matter of time before Ivy gets raped again and filled with cum. Cause right now
it doesn't matter if she gets pregnant or not, there is simply no drawback to it, she just looks cute with that belly.
