Suggestion: Male survivor can be found in random building and you could either recruit or trade with them
Recruiting: you can recruit a maximum of 2 survivors and you can give them weapons along with sharing the food water and energy with them along (most of them will have different perks when they join you)
Trading: you can buy the basic essentials like food and water and sometimes weapons with credits while also being able to sell food for credits
Scenes and encounters: being fully aroused allows (some of the enemies) to have a threesome with all of you (you are able to change the position of your party making them spread out)
