Perversion

Alongside Resistance, Perversion is one of the 2 primary mechanics governing sexual interaction and parasite infection in Part 2, Part 4 and Part 5. Even the Main character has a perversion rating and it is displayed for most characters you can infest in these parts.

When infesting yourself as early as part 1 the game tells you that perversion is how you react to sexual acts. In part 2 your perversion primarily affects the rate at which infected characters will trigger sexual events during the day (when you return home). Once infected most events will increase perversion by at least 1 and NPCs will stop triggering detection events on their own (Although they can still be caught as opposed to trying to turn you in). Some events will also reduce resistance and those events become more likely as perversion increases. This means that once infected as long as the game does not end from detection eventually any NPC will reach 100 perversion and -100 resistance without any further interaction with Chet/Chloe.

Perversion does affect a characters willingness to engage in sex but perversion rises so fast that once an NPC is infected and has broken the resistance barrier of 60 it is very unlikely that perversion will not be maxed out. Perversion can go above 100 but it gets reset back to 100 once you sleep. Nothing reduces perversion.

Of course various events will affect an NPCs Perversion:


 * X behaves as normally as possible. The infection increases his/her perversion slightly. +1 perversion
 * X masturbates as frequently as possible to relieve his/her arousal. +3 perversion
 * X has sex with Y. Their infection drives them deeper into sexual depravity. +5 perversion each
