If Strix catches you, you're dead. Run Fluffy 5, Symbiotic 3 and Harmonious 5 to save yourself from a headshot and a 2nd bodyshot. Or run Fluffy 4 and buy Haven if you're confident he won't land a headshot.
Moji has a hard time aiming around Vivian's shield, so to deal with her, flank. Be weary of sensors and If Vivian placed one in the flank route, take it out, wait a bit and strike later once Vivian assumes you've left and busies herself.
