Hahaha good one! I was even thinking about Debtors post-apo at some point but zombie invasion sounds cool and cheesy toooo <3
If Debtors were the Walking Dead than Vito definitely would be Negan xD
i mean most sex games tend to make lust driven zombies you could go down a more feral route with the zeds instead of them spreading it thru biting maybe they drag people to their lust nests which have a spore that causes your mental abilitys to only show lust meaning they are zombies but their pure desires are mainly lust and fucking
you could make a few screens with zeds where they are sated but our debters could find themselfs with infected who are slowly turning they can choose to fuck them or hide if you hide it would be random if they find them but if their found after hiding the infected would drag them back to their nests in turn ending the game in a infected gameover screen
but if you let them use your body they might even be passive enough to let you choose how you mate them
you could make it based on balancing your infection as well as their fluids could be the thing that causes the spores to spawn so to get rid of them youd need to have sex with someone who isint infected doing so the mix of two love juices mixing aka 2 diffirent dna's mixing would cancel it
you could even go 1 stage more and make some cool sexy designs for the infection and let the debtors have a infected form imagian them fucking vito and in turn they scare him by showing their infected forms if your infection is high enough you could even corrupt him and make him spread it thru their ranks at which you could try to lower it again both ruining the hyena's but also curing yourself
my thought could be to ruin him you have to get high alpha state on either of the debtors doing so gives both of them a more dominating personality using the infection could also let you mess with peoples minds you could force him to be less dominate with the spores then breeding him would let you assort domination over him because the spores would remove defiance and then the point that he finds out hes infected you could make him scared of spreading it while also turning him in 1 blow
and i mentioned apoc because you could do things thru a metro style map over a on top side map
think metro where you travel thru them to each location you could setup checkpoints on the map and small tunnels this also gives you a moduler style and its much easier as you can make everything outside the main design either brown like dirt or grey like concreate
