What the developers have to say:

Why Early Access?

“From the start of the successful Kickstarter campaign my goal with ZERO Sievert has been to be as transparent as possible with the community and to make the best single-player extraction shooter I can. Fan feedback has played a major part so far in building a great game and strong community and I intend to continue that through to 1.0.”

Approximately how long will this game be in Early Access?

“While I don't have an exact date in mind, I'm expecting the Early Access period to run for about a year.”

How is the full version planned to differ from the Early Access version?

“The full version of ZERO Sievert will have more maps/levels, more weapons and customisation options, and we're leaving our options open for additional features and control setups.”

What is the current state of the Early Access version?

“At Early Access release the game will have 5 procedurally-generated areas to scavenge and over 150 weapons and weapon customisation options. On top of this, the modular quest system has already been implemented, representing the core systems and gameplay loop.”

Will the game be priced differently during and after Early Access?

“I expect the price to increase slightly at the 1.0 release to reflect the added polish and content, and as a way to reward early adopters during the Early Access period.”

How are you planning on involving the Community in your development process?

“Building ZERO Sievert with the community was always part of the plan, since the project's inception on Kickstarter. Any and all players keen to provide feedback are welcome in our Discord server of over 20k people where we have bug reporting, feedback requests, and community contests.”

About This Game

The world has ended. ZERO Sievert charges you with scavenging equipment across multiple areas, all set in an atmospheric fictitious post-apocalyptic Eastern Europe setting. Your base of operations, the bunker, is filled with traders, modding stations, and areas to make your own, providing you with progression across your excursions into the wild.

Once you’re out in the wilds of the wasteland, however, the situation becomes a lot less secure. Across the five biomes of the game, you’ll initially be armed with little more than a gun and a bottle of water, after which point it’s up to you to recover items, take out bandits, and most importantly, get back alive.

And be warned; the nuclear fallout may have impacted some of the local wildlife…

A wasteland to explore

Procedurally generated maps make every journey different, with ever-changing hiding spots, loot locations, and layouts. With over five maps to explore, be sure to adapt and learn each one's secrets to get in, get out, and get better.

Full weapon modification

Hunt in a way that suits your playstyle, with over 35 unique guns and 150 mods that can be combined to make you the biggest threat in the wastes of ZERO Sievert. Create a weapon that suits your style or focus on stats to become the ultimate hunter.

Looting and questing

Multiple questlines guide you through the world of ZERO Sievert. Through talking with a range of characters you’ll slowly unravel information and lore about the world that’s been left behind. Alongside this, there are more than 100 different items to loot which can be used to craft new items, upgrade your own base, and trade.

Mature Content Description

Blood spatter and violence depicted in a pixel art format. Some adult language can be found in character interactions and dialogue.
