STALKER 2 Armor: Slots, Protection and What to Wear

The four values

Physical protection covers bullets and melee. Radiation protection decides whether artifacts cost you drugs or nothing. Psi protection matters near specific structures and enemies. Chemical and thermal protection matter in anomaly-heavy areas and in a smaller number of scripted locations. No suit is good at all of them. The suits with the best physical protection usually have weak anomaly protection, which is the trade the game is built on: you are choosing which hazard to be safe from.

Slots are the real stat

Every suit has a number of artifact slots, and those slots are where your build actually lives. A suit with five slots can carry weight artifacts, radiation clearing, and two combat bonuses at once. A suit with two slots forces a choice. This is why “the best armor” question has no single answer. A heavier suit with more slots beats a lighter one with better raw numbers for a player who farms artifacts, and loses to it for a player who travels light and fights a lot.

The stages

Early. Whatever you loot or can afford. Prioritise physical protection and don’t bother upgrading; you will replace it. Mid. The first suit with a good slot count and decent radiation protection. This is the one worth upgrading, because upgrades are permanent and follow the item. Late. A specialised suit for anomaly work and a separate one for combat. Carrying both is impossible, so most players settle on the best all-rounder and accept that no single suit covers everything.

Upgrading versus repairing

Upgrades are permanent improvements and are tier-gated by the technician — see the technician page. Repairs restore durability and cost coupons that scale with the item’s value. The economic rule: upgrade the suit you intend to keep for the rest of the game, and repair everything else. Repairing a suit you are about to replace is the most common money leak in the early game, and the armor repair page quantifies it.

Weight is part of the decision

A heavy suit plus a heavy weapon plus loot is a character who cannot run. That is why weight artifacts and slot count interact: more slots means more capacity artifacts, which means the heavy suit becomes viable. The weight artifact page covers that loop, and it is the reason two players with identical armour have very different experiences.
