With its 1.0 launch, Zero Sievert has firmly planted itself as one of the more unique and brutal top-down survival shooters. Whether you’re returning after a break or just now stepping into the irradiated forests, industrial ruins, and bunkers of Zov, this guide delivers a treasure trove of tactical knowledge. Here, we focus on practical, often-overlooked strategies to elevate your play without spoiling the joy of exploration. If you’re after those hidden mechanics, optimization tips, and decision-making insights—this one’s for you.

Building a Stockpile Early On

One of the most efficient long-term strategies is to scrap weapons and armor—even if you don’t plan to use them. Every spare piece turns into crafting materials that save you time and cash later. Begin building a material stockpileearly, and you’ll thank yourself when entering more lucrative zones.

Need to stretch your inventory capacity? Try this loop: load up with loot, extract, drop items at the exit, and re-enter.Items persist until the end of the raid, letting you make multiple quick runs without ever returning to the bunker. Want even more time? Opening your inventory or looting halts the extraction timer, buying you precious seconds to grab just one more container.

Be cautious, though—bleeds and radiation don’t wait. You can take damage while navigating menus or upon returning to the bunker. Always head to the doctor immediately after returning from a mission.

Hidden Stashes and Smart Looting

Keep an eye out for ground patches with loose sticks—they mark hidden stashes. These can hold valuable, randomized loot. Combine this with a well-timed airdrop sprint and you’ve got a strong route to riches.

Speaking of airdrops: the longer they’re on the map, the more looted they become. The early bird gets the gear. Sprint to them quickly or risk fighting over leftovers.

Guns at low durability may jam mid-fight, which can be fatal. Rebind the jam-clear key (typically V) to your middle mouse button for fast reaction without losing movement control.

Surviving Radiation and Boosting Perks

In high-radiation zones like the industrial map, always bring radiation booster stims. These lightweight life-savers are especially vital during events like green rain—which causes rapid radiation buildup. One stim can be the difference between walking out or dying meters from extraction.

Perks can be freely reset at the bunker, allowing you to tailor your loadout to specific missions. Planning a loot-heavy run? Respec into Value Finder or carry weight perks. Need to kill tougher enemies? Choose weapon-specific upgrades like Impaler Shot, perfect for slowing mutants like Bigs.

NPC Allies: Eagor and Junker

On the Forest map, you’ll meet Eagor, a reclusive NPC offering a quest. Finish his mission and unlock a repeatable loot cache whenever you revisit. It’s passive income with no downside.

In Makeshift Camp, look for a manhole entrance to find Junker, a vendor who sells scrap and rare items. Buying scrap from him means you can carry more valuable items instead of heavy loot, optimizing both weight and profit margins.

Bosses, Food Buffs, and Smart Module Choices

Zero Sievert’s boss enemies are no joke. They come with unique gear and require solid tactics. Always come prepared, and never underestimate a new threat.

Keep food and hydration in the green:

• Food buffs increase carry weight.
• Hydration buffs increase looting speed.

This ties directly into your efficiency. Loot faster, move heavier, and spend less time in danger.

When building your base, start with the Workshop and Bedroom modules:

• Workshop lets you repair gear with scrap, avoiding costly repair kits.
• Bedroom boosts resting recovery and reduces food/water use.

Consider the Recycling Center early on—it increases scrap yields. Stockpile materials faster, then replace the module once you’ve built your reserve. You’ll likely get a Storage Module for free through either Eagor or General Ovich’s quests, so save your parts for other priorities.

Gear Management & Weapon Optimization

Equipping a weapon removes its weight from your inventory. Keep your second slot open so you can carry another gun out of raids for scrapping.

Most attachments weigh 0.1kg and have solid resale value. If you’re short on rubles, attachments make excellent filler loot.

Struggling to find corpses?:

• Watch for crows circling over them.
• Lower grass density in settings to make bodies easier to spot.

Healing for Free, Saving Your Rubles

The Barman and Doctor offer healing, food, radiation removal, and armor repair—but it costs. A cheaper alternative? Rest in the Bedroom module or Bunker beds. You’ll heal, recover energy, and even remove radiation free of charge.

Only skip rest if you’re trying to avoid time advancement for mission reasons.

Bullet Physics, AI Behavior, and Tactical Combat

Except when scoped, bullets in Zero Sievert have travel time. With scopes, you gain hitscan shots and extended vision. That means you can engage from beyond enemy view range—huge advantage.

Be aware: human AI is smart. Repeat-peeking the same corner makes them respond faster, even use grenades. They remember your last position. Switch angles, flank, or reposition to regain the upper hand.

Crosshair indicators help too:

• Red edges = reduced damage due to range.
• Red center dot = obstacle in your line of fire.
• X-shape = target is out of range entirely.

Use the right weapon for the distance. SMGs or pistols shine up close, rifles rule at range.

Trading Smart and Managing Trader Cash

Traders run out of cash. To work around this, save high-value, single-slot items like military circuits or jewelry. When you need to make a big purchase, sell these after your buy to reclaim funds.

Don’t forget to use the Track feature on desired modules. You’ll mark required materials for easy identification mid-raid.

Faction Logic and Reputation Nuances

Zero Sievert’s faction system is intricate:

• Green Army and Crimson Corporation are mortal enemies.
• Joining one locks you out of the other forever.
• Reputation caps at 600 unless you join a faction—then you can access higher-level gear.

Green Army leans on Eastern weapons, Crimson Corp on Western gear. Make your choice based on your weapon preferences.

You lose 0.5 rep for attacking a faction member, and 1 rep per kill. Occasional kills for gear are fine—just don’t overdo it.

You can farm rep by trading: every 20,000 rubles worth of sales grants 1 point of rep. This is a great method for unlocking elite gear like Tier 3 night vision goggles, which require 850 rep and faction allegiance.

Night Raids: Risks, Rewards, and Visibility

Nighttime raids are double-edged. Vision is reduced—for you and enemies. Human AI has less detection range, making stealth and sniping more viable. They use flashlights, so you can spot them easier, but beware—Hunters don’t, making them a serious backstab threat.

Invest in proper gear:

• Night Vision Goggles 1 = Poor. Avoid.
• NVG 2 = Decent. Requires 550 rep.
• NVG 3 = Best. Requires 850 rep + faction join.

Otherwise, a headlamp or torch might suffice, but the NVG 3s give you a real tactical edge.

Miscellaneous Quality of Life Tips

• Unload ammo from enemy weapons you loot.
• Right-click the map to place HUD markers—use multiple and remove with another right-click.
• Don’t skip the tutorial! It’s not automatic—launch it from the main menu.
• Press H to teleport inside the bunker. A small but helpful time-saver.
