Thought I'd post this to anyone playing the game and cant find the ritual and clan upgrades.
Copycat/Wristbaldes #2: On a brige-like platform around the corner from the multi-story car-park.
Dead Man Walking/Combistick #2: In a rooftop corner near the "Arms Deal" location.
La Familge/Speargun #2: On the mansion roof (use the conservatory at the side to get up.)
Death In The Family/Glaive #2: Pretty obvious
Under The Gun/Plasma Canaster #2: On the rooftop of the building closest to the ocean (there are platforms to get up.)
Machine Men/Wristblades #3: At the bottom of the arena, opposite from where you start.
Sink The Shipment/Maul #1: Obvious
Monster Squad/Glaive #2: In the fire to the right of where you start.
Rescue/Speargun #3/Combistick #3/ Smart Disc #2/Maul #2: Grap a soldier and move him in front of a ID scaner to battle a hybrid and get the weapons (3 in total, disc and combistick are found in the Predator Testing room.)
10,000 Ways To Die/Glaive #3: Before you kill the final soldier, cross the bridge and go around the building.
Hot Time In the Old Town/Plasma Canaster #3: On the holographic church rooftop.
If It Bleeds.../Smart Disc #3: In the generator room when you've destroy the other engines.

Hopefully that helped someone!
