How do you rescue cassie from the Don without ending the game?
I don't want to ruin it so here's a brief run through, find and talk to everyone who has a portrait (image/character) inside the entire new ark city (including slums). Then after talking to all 4 (I think) characters head to the slums to find a npc near dom's hideout, spend 1000 credits and find him again the next day at the gentleman's club complete dialog and the "quest" after, afterwards find a certain character that has authority (hint: she has red hair and her furry form is a fish thing? forgot what it as called) then you should be 100% prepared if all your stats are like 99 and plus other buffs like intoxicated, invigorated and etc
