📋 About This Mod

Easy & Simple cut + paste + extract installation. No mod loaders needed. Destroyed META. Build your own META, your own cursed guns, go nuts! Extra & cut contents. Recycling vanilla assets. An extremely modular, scripts only, simple overhaul

NO REQUIREMENTS! NOT EVEN MOD LOADERS!

Just extract into: ZERO Sievert\ZS_vanilla\gamedata

This mod is NOT realistic or attempted to be realistic, 2D top down nature of the game helps that fact.

Mod is heavily focused on gameplay, fun and making things "reasonable/agreeable" while making everything a viable option.

MOST of files PROVIDED are dependent on each other! You may change and edit as you'd like though.

It is possible to only make use of (and these are required for each other to work):

weapon.json

caliber.json

If you want to make use of my new AI, add these to the list (requiring the above files):

npc_preset.json

npc.json

Primary objectives:

1/ Eliminate the game's stale "meta" rosters such as AA-12 + AS-VAL...

2/ Eliminate inconsistencies, such as weight, stack, value, availability, etc...

3/ "Fix" traders of all factions, now Green Army is an equally attractive choice vs Crimson Corp.

4/ Change how Economy works, providing a consistent experience, planning your gears is even more important now.

5/ Allow "Loner" run to be MORE viable, as in you're not joining any faction.

6/ Some sniper rifles can now be used WITHOUT a magazine, reload after every shot, First Bullet perk BUFF this.

7/ Actually make SubSonic ammo a VERY viable option, especially early and mid game.

8/ By buffing SubSonic, STEALTH is now extremely viable, role play Splinter Cell all day every day :)

9/ Greatly expanded and overhauled attachments interchangeability + stats. NO MORE META!

Secondary objectives:

1/ Add humorous descriptions, some of which are actually helpful tips.

2/ Added more items & guns through recycling vanilla game's assets (completed with stats, behaviors and attachments)

3/ Change how ammo and weapons behaves. Dev attempted this, but it's only slightly better, not a big improvement.

4/ Buff bosses to behave more like players, providing them gears and consumables to sustain their efficiency and lethality.

5/ Change vanilla AI, fix some old problems such as unresponsive to incoming sniper fire, they will push or counter snipe if possible now.

6/ Overhauled loot pools for varieties. ex: You get a chance to find guns or armours inside BIG from its last meal.

... MORE OVERTIME!

There is no need for a mod loader (but I'm not stopping you from using it).

It should be compatible with almost anything that's not replacing these files, mods or otherwise.

You could use this mod in place of vanilla scripts as the base for other mods, it works.

You could use any other mod ON TOP of this mod and that should work too without problem.

Since these are merely script files, in theory it should be compatible even with new version of the game.

MIGHT NOT BE COMPATIBLE with new version of the game if dev added new maps / zones / bosses / spawns / etc...

But it should still works, just no new stuff in-game. Do notify me if that happens, relatively easy fix.

Everything else are optional. I've also provided a zip file containing all of the default scripts so you don't have to verify integrity when needed.

Appearances:

Much like players, most non-faction AIs such as hunters / raiders / bosses are capable of changing their armours and appearance.

Look can be deceiving, stay vigilant! (but they're restricted from equipping major factions' armours to avoid confusing players)

SubSonic buff:

The lack of "protected" area means any spot on the body are treated, and damaged, equally.

This make the nature of SubSonic munitions obviously bad and unfitting with this game, it should not be in the game at all.

I've chosen to make Subsonic the most overpowered munition type in the game by hyper buffing its penetration.

To compensate for this, SubSonic got the shortest range of all munition types in the game, tied with shotgun.

This encourage close range, fast and precise execution because:

Most guns got a good range buff except for shotguns, even those got a slug range buff.

NPCs are now even more lethal than before, their engagement range (but not their detection range) also increased.

This will be even more evident as you progress, enemies response faster, more precise and even snipe you.

Stealth became vastly more effective against improved AI. If you got a suppressor, and stay out of sight.

Enemies might be aware
