#31 – You’ll find this one above the frontend of the red traincar.
#32 – You’ll come across a split in the train tracks, then start on the catwalks in a new room. The watcher is floating in midair to your left as you enter.
#33 – In the next area where you are asked to "take the lead", to your left are some burning debris and a traincar. Look inside the traincar for it.
Scene 0-2 – The Womb
#34 – You can find this in the area where you first engage the enemies.
#35 – When you’ve cleared the area, move forwards but keep an eye on the watcher hidden in an alcove to your right.
#36 – In the area where you’re ambushed and your other two allies are on top covering you, look above where they are and you’ll see it.
#37 – When you come to the scene where you fall off a collapasing bridge and are surrounded by spiders, look straight up and its in midair, near the cracks where sunlight is shining in.
#38 – This one is tricky. After escaping from the spider things, you will again come to a split. Take the left path to another split, take either path and pay attention to the wall in the middle (i.e if you went left, look at the wall on your right and vice versa), go forward just abit while paying attention for a small gap in the wall linking both paths which is where the Watcher lies.
#39 – Finally you’ll emerge at the bottom of a huge pit. Look downwards towards the deep abyss and you’ll spot Watcher #39.
Scene 10 – Pharyngeal Carcinoma
#40 – In the room where you fight Thanatos, I think this is behind where you start. Sorry all the dodging around messed up my sense of direction.
#41 – When you come to the big transforming room with lots of moving pillars and where you need to defeat 5 groups of enemies to proceed, this Watcher is immediately above where you start.
#42 – After the cutscene with the Dreadnought running off, you will enter a massive cavern. Onwards abit and you’ll jump onto a pillar which immediately sinks and two brutes appear out of nowhere. The Watcher is behind the brutes in a gap of the wall of the next pillar. This is very tricky what with two brutes (on Hard mode) rushing you in a small contained area and giving you very limited time to nail it before it goes out of sight.
#43 – After riding two granulas and climbing upside down, after you get off the ceiling and land, immediately go the ledge outside and look downwards to your right, you should be able to spot it. This is BEFORE you leave the chamber via the exit on the ceiling.
Scene 10-2 – Gynoecium
#44 – During the fight with the Dreadnought, look straight up in the middle and you’ll spot it.
Scene 11 – Clavicle
#45 – In the first area, there should be a sniper on the far side and when you are moving towards where he was you should spot an ammo box. When you finally reach where the ammo box is, look forward towards where you started the level and a dome with blue roof is to your left. Above the dome you should be able to spot the green glow of the Watcher.
#46 – After shimmying and you get off. Turn around facing the wall and look upwards to see #46.
#47 – After more shimmying, you’ll reach a checkpoint and one of those Crystal Security Cores. The Watcher is behind it.
#48 – Move forward abit and you’ll fall down and will be facing a Rocket Brute and two Nosferatu soldiers. To the left of his platform you’ll find the Watcher floating in mid-air.
Scene 12 – Cavitas Cranii/Diabolosis Soma
#49 – This is during third fight with Thanatos after he’s transformed into that big giant ugly black thing. Circle around him to the left and you should see the Watcher underneath the winding path that leads upwards.
Scene 13 – The Seed of Gnosis
#50 – This is inside one of the crystals that hold the embryonic maidens (Filena clones). It’s very near to the Core in the middle.
