S.T.A.L.K.E.R. 2: Heart of Chornobyl

*Temporary note about a potential required third missable for helping The Ninth on side mission The Lost Boys. See comments.

*Temporary note regarding save tracking. MIGHT be all of the saves within a slot, not multiple slots. More feedback needed.

So, this achievement is somewhat of a nightmare. 2 missables, for starters, lots are a bit tricky to actually get to (locked doors, puzzles, door codes, accessed from an anomaly a kilometer away, only accessible after some missions) and there is no decent way to keep track of the blueprints you have/still need. The map size and limited fast travel are also a bane for this achievement.

Onto the good: The blueprints track across all of your saves, so if you're like me and missed one of the missables, you can at least reload an older save if you have one. Might take you hours, but better than having to get all 77 on a new save.

To track blueprints you still need, unfortunately the only way is to have the gun/armor in your inventory, open the PDA, tab over to upgrades, and inspect each individual part on the item. Missing blueprints show up as a little blue icon in the top right of the part you're looking at. Not great, not terrible. At least there's a way.

Lots of the required armor and guns can be found throughout play(looted or bought), though the exoskeletons are somewhat rare (1-2 locations for each at best) and I recommend keeping one of each variant for exactly this purpose. Some will have to be found, or you can just make a list of the ones you haven't found and track their blueprints another way. The ones with blueprints are:

Weapons:
M10 Gordon
Rhino
APSB
Integral-A
Zubr-19
VS Vintar
Grom S-14
AS Lavina
Kharod
Dnipro
M701 Super
SVU-MK S-3
M860 Cracker
Saiga D-12
Ram-2
RPM-74

Armor:
Berill-5M Armored Suit
SSP-100 Discovery
PSZ-12V Bulat
PSZ-9D Duty Armor
PSZ-9I Falcon
SEVA Suit
SEVA-V Suit
SEVA-I Suit
SEVA-D Suit
Operator Exoskeleton
Brummbar Exoskeleton
Exoskeleton
Liberty Exoskeleton
Bulwark Exosuit
Cuirass Exoskeleton
Shield of Duty Exosuit
Sphere M20 Helmet
Ballistic Helmet
Mask-1 Helmet
Tactical Helmet

The two missables:

Spoiler: Side with the Noontiders on "Wishful Thinking" (~1/3 the way through story), and make sure you grab the blueprint during "Happiness for Everyone" (~2/3 the way through). Pharcyde confirmed you can come back here later, but the sewer is not accessible if you side with The Ward.


Near the end of the game, choose Polissya Hotel during "Down Below".

How you tackle this monster is up to you. Good luck.
