ZERO Sievert 2 Skills and Systems
Steam describes four skill paths—Combat, Survival, Recon and Ingenuity—plus weapon and map mastery. These are published design descriptions, not a promise that every system is fully present in the November 2026 alpha.
Four skill paths
The official description says a Hunter develops through Combat, Survival, Recon and Ingenuity. It presents growth as connected to how you play: direct fights, scouting and quieter survival approaches develop differently. The store does not publish a complete skill tree or point-by-point build recipe.
Weapon and map mastery
Weapon Mastery is described as growing with the weapon class you use, while Map Mastery is earned separately on each map. The store advertises more than 30 modifiable weapons for the planned game, with ammunition choices that trade penetration, damage and cost. It also warns that poorly maintained weapons can jam. Do not read the full advertised arsenal as the alpha’s item list.
Anomalies and relics
Anomalies are dangerous paths through Zakov; the store recommends testing ahead with bolts. It describes relics as equippable objects with passive effects, with some stronger ones granting active abilities. Use can destabilize a relic and eventually cause a Catastrophic Failure. Exact values, locations and alpha availability need build-specific verification before a guide can claim them.

The store describes them for the planned game; the alpha announcement does not confirm every system in its limited slice.
