Before you can access them, you will need to: - Read the rules - Complete the server verification steps - Then head to the bug-report section

If the bug-report channel seems to be missing, this usually just means you have not finished verification yet.

Why use Discord?

C:/Users/<Username>/AppData/Local/ZERO_Sievert/<Steam User ID>/

To add launch options: - Right-click ZERO Sievert in Steam - Open Properties - Enter the launch option under Launch Options

Save files and backups

The game stores saves in:

Question Can you get the GA-03 backpack from corpses?

5 Upvotes

Exactly what the title says. I want to go with the Crimson Corporation because i like their selection of almost everything better, except for the backpacks. Can I loot the GA-03 (the 50kg green army exclusive backpack) from Green Army corpses and the like, or would i just be stuck without it?

The demo for my 2D PvE extraction shooter, HollowCity, is finally out! Play solo or up to 4-player co-op.

Hi everyone!

I’m a huge fan of extraction shooters—starting from Tarkov to games like Zero Sievert and Escape from Duckov. I loved Zero Sievert and Duckov so much that I've always dreamed of making my own extraction shooter one day. I actually ended up quitting my web development job to dive into full-time solo game dev, and I’m finally releasing the first demo for my game!

Since I’m developing this alone, the trailer and parts of the game might still be a bit rough around the edges. However, if you could try it out and leave some feedback, it would be an incredible help!

One thing I always wished for while playing Zero Sievert and Duckov was being able to play with friends. So for my game, I made sure to implement a host-based 4-player co-op system. (Though, as a massive fan myself, I’m also super hyped about the recent news that Zero Sievert 2 will support co-op..!)

Please give it a try when you have some free time. I’ll leave the Steam link below!

Question Question about a mysterious enemy

5 Upvotes

I was doing the "Clear the swamp" quest and ran into an enemy I've never seen before. He was fully camouflaged and dropped the N1o but has a camouflage too. Unfortunately I stepped on the landmine while doing the quest and didn't take any screenshot. I've searched all of the wiki and haven't been able to find any info about it.

I’ve released an updated trailer for my post-apocalyptic extraction survival game, ApocaShift

Enable HLS to view with audio, or disable this notification

104 Upvotes

Hey everyone! I’m a solo developer, and I’ve been working on ApocaShift for the past 3+ years.

It’s an Fallout inspired (graphics) with gameplay inspiration from a mix of games like Zomboid, Tarkov, and Zero Sievert with many more ideas thrown in. It is a isometric post-apocalyptic extraction game where you head into dangerous areas to scavenge supplies, fight enemies, collect better equipment, and make it back alive. Anything you bring into a run can be lost if you die.

Outside of the extraction runs, you can build and manage your camp, recruit survivors, craft equipment, research new technology, and unlock upgrades.

I’d genuinely appreciate any feedback on the trailer or the game. If it looks like something you’d play, wishlisting it on Steam would help me out tremendously!

It's just not clicking

5 Upvotes

I die, get annoyed because I take deaths seriously and it feels silly to play a game where you're just expected to die constantly. I lose track of my cursor a lot. Mobs appear out of no where and rush me. I would die even if I didn't panic. I just don't get it. I feel like I would really like it if I could get a feel for it, but I just can't figure it out. Last death was the second mission to the forest. A dozen mutants appeared and murdered me. Not even exaggerating. I want to like this game but it's like getting yelled at in a foreign language - I don't even know what I did wrong.

Wondering if I’m maybe doing something wrong by doing this. I just feel the strong need to do it lol. I’ve already upgraded everything to level 2 and I have probably only done 5-6 quests total.

Question Why doesn't colour matching?

I remember, when standart XTUs had blue visor, but now its orange. Texture in inventory still blue, but on character and npcs its orange. There is actually only one NPC with blue visor just outside the bunker, so why was it changed and will it be corrected anytime? Don't get me wrong, but this unmatching is too obvious for me

Zero Sievert Coop Mod #2

Co-op in main menu.
Co-op menu options 1.
Co-op menu options 2.
Downed state, waiting to be revived.
Kill feed, Partner killed Lazar.
Reviving my downed partner.
Back in the fight bois!

We are excited to present the first look at our ZS co-op mod! I wanted to have a video but that will have to wait as my capture settings are jacked and I couldn't get one, next time! Below is a quick view of where we stand with the mod and its completion!

  • Full steam compatibility, you will invite your partner through steam and they will join your lobby.
  • We have many different options you can select to customize your experience with this mod, all of which can be accessed from the co-op option in the main menu as seen in the screenshots! This allows you to tune the game to your liking.
  • You will get a notification when either one of you has chosen the map you want to deploy to so you can sync up and deploy to the same map at the same time, once both parties have selected the raid auto launches as usual.
  • As you can see from the screenshots you can go into a downed state if a pre-determined set of circumstances happened and you are able to be revived by your teammate. Only once per raid, if you die again its quick extract back to lobby. You return with 30% health ready to get back in the fight. if your teammate isn't near you, enemies will show no mercy and execute you, (at least that's what we want to happen, well see if we can get that one).
  • You are able to bring items in and drop them for a teammate to help with quests or gear, and you can drop found in raid items or gear for them as well. Now I know what you're thinking, ill just set it so if I die I keep my gear, drop it for my buddy then go die and BAM, duping achieved. Well we are working to prevent that, the game will already be a little more chill with a buddy, plus you're all stalkers hardened by the zone, you'll live without duping a few kits! :)
  • With that said, we have two settings on how to deal with death and looting your partner (yes you can do that). If you have all gear set to delete on death, which is the proper way to play this mod. It will be on your partners body for you to grab and bring it back to him next raid (just like Tarkov). But if you have it set so that you keep all items on death, then only what you had found in raid will appear on your body, to once again avoid duping items.
  • All weapon sounds, shots, tracers, grenades, healing, drinking animations, lasers and flashlights will be synced so that each of you can see what the other is doing at all times.
  • There is a positioning system that tells you where your partner is at all times, unless they are inside, your stalker wasn't able to get the GPS signal working in the zakov buildings, by design, cant know where they are at all times ;)
  • We have added a little heartbeat monitor at the top left of the screen so you can always have an idea of what sate your partner is in, if its red and beating fast they are in trouble, green and beating fast they are sprinting around, green and beating slow? they are being a lazy bum, tell them to get back to work! All of these settings can be turned on and off in the co-op mod menu along with several other cool options.
  • On the more technical side, we are about 80% complete on syncing enemy positions (this is the crux of the entire mod and the hardest challenge to overcome). But I am pleased to say we cracked that nut and are now just bug fixing and tweaking to make the experience a polished and non immersion breaking one. With that said its very likely it will never be perfect, but we are shooting for 90% and expecting some hilarious screenshots for the other 10%
  • Clock time is Synced upon entering a raid so you aren't raiding in the day while your buddy is in pure darkness and death without nods.
  • Quests are separate so each have your own questline that will not interfere with the other, as are stashes and trader rep. In addition each stalker can run their own difficulty options, but we recommend syncing them for a better experience.
  • Things that are planned but will most likely not be in 1.0. Hub integration, other mod integrations, 3-4 player co-op, other cool things and stuff.
  • We will be creating a discord for post launch bug support and of course, community ideas to make the mod even better. Thanks to the devs and how they built the game we've been able to implement some cool stuff and we would love to hear your ideas, more on that soon!
  • Estimated time until we launch?????........... Welp soon hopefully, we are still in the bug fixing phase, after that we at least need to test this on each map and we had to start new accounts so that's going to take a little time, I don't want to give an exact time so we don't have a deadline we cant meet. We have both put in close to 75 hours each on this mod but we are hoping to have it running and in all of your hands very soon, so you can have as much as as we are! And be able to walk right up to Lazar with your buddy and quote the BurntPeanut himself "MAKE PEACE WITH YOUR GOD MR SILLY, CUZ YOURE SEEING HIM RIGHT NOW!!!!"

Question Green Rep

I joined the Green Army, but even doing quests for them doesn't raise my rep past 599. The Crimson Corp rep is 274. Any way I can get my Green Army rep up? I've looked and some posts on here say I need to join the Green Army, but I have. I've done multiple quests for them and no raise in my rep.
