$19.99ZERO Sievert Loot fast, get out alive
ZERO Sievert is a tense top-down extraction shooter set in a ruined Eastern Europe.

Built for extraction fans who want careful solo PvE pressure.

Get in, loot, get out alive
You pick a map, bring your own loadout, and hunt for weapons, gear, and 100+ items to craft, trade, or feed into your bunker upgrades. Bandits, hunters, ghouls, and changed wildlife are all working the same ground. Death costs you what you carried, so every full backpack turns the walk to extraction into a calculation: push one more building or leave while you still can. The top-down pixel art keeps everything readable, and the sound of steps closing in does the rest.
Guns, bullets, and preparation
There are over 50 guns and 150 mods to mix into something that fits how you hunt. Ammo types, range, armor penetration, and weapon length all matter, so you plan around the job: a shotgun with slugs for infestations, a scoped rifle with piercing rounds and grenades for a human boss. Surviving levels your weapon skills and hunter perks, improving reload speed, damage, and movement. It is a thinking shooter where the work before the raid decides a lot.
A bunker to build and sides to pick
Between runs you return to the bunker, with its traders, modding stations, and rooms to upgrade. Quests from its characters pull you through the lore of Zakov while unlocking better options. You can also side with the Green Army or the Crimson Corporation, earning reputation for faction quests and high-tier loot.
Good to know before you drop in?
Can you play it solo?
Yes, it is single-player only. Every threat is AI: bandits, hunters, mutants, and bosses.
How punishing is dying?
There is a hardcore-style option where death loses what you brought, classic extraction rules, alongside a more forgiving standard option that keeps your things. Finely adjustable difficulty settings also let you tune enemy health, loot, and experience to suit you.
Do you need to learn survival needs?
Yes. Hunger, thirst, carry weight, durability, weapon jams, and night darkness all shape a run. You start with little, so water, torches or night vision, and the right gun for the task matter from the first maps onward.
