About

What is DeciRemnant?

Decimation is BoehMod's zombie apocalypse mod for Minecraft 1.7.10: loot crates and car wrecks, guns and attachments, traders and bandits, military zones, and survival bars for food, water and blood. It was built around BoehMod's own servers, and when they closed, much of it stopped working.

DeciRemnant brings it back. It fixes everything that waited for those dead servers, so the whole mod runs in singleplayer and on your own server, and it adds what an abandoned world needs: generated cities, military bases and airports, safe zones, smarter soldiers and new guns.

One jarDecimation with every fix and the new world, for Forge 1.7.10.
Alone or togetherSingleplayer, or your own server for friends.
Free and unofficialA fan project. Decimation belongs to BoehMod.

Singleplayer

Everything works on your own

Decimation left the loot, the zones and the supply drops to its servers, so in singleplayer they never ran. Now they do.

  • Loot crates and car wrecks fill and refill
  • Safe, military and police zones protect and spawn
  • Supply drops fall from the sky
  • Traders, bottlecaps and humanity count
  • Armour stops soldiers' and bandits' bullets

World

Cities to survive in

The new world type Decimation builds whole cities as you explore, filled with Decimation's own props: towers, offices, shops and homes on real streets.

  • 4 to 64 districts in every city
  • Highways, an underground railway, rivers and bridges
  • City refuges, survivor camps and military bases
  • Fenced wasteland districts, some with an airport

Arsenal

New guns in Decimation's style

Our own guns, built part by part the way Decimation's are, with its animations and attachments. Soldiers and bandits carry real loadouts by rank, so a patrol's weapons tell you how dangerous it is.

  • MAC-10 and UMP9
  • HK416, also in tan, and Mk18 Mod 1
  • EOTech and ACOG sights

What it adds

And more

Safe zones

Survivor camps and city refuges with traders, guards and a clinic.

Bases and airports

Military bases in three sizes and airfields in wasteland cities, locked rooms and loot inside.

Soldiers and bandits

Ranks up to elites and juggernauts, with snipers and rocket teams. They hear your gunshots and come looking.

Infected

New kinds of infected, and a night frenzy: faster and harder hitting after dark.

Your own server

The same jar runs a Forge server for your friends; the server guide has every step.

Updates in the game

Changelog

What changed

0.65.0 20 October 2026 · pre-release

Singleplayer fixes and world generation for Decimation (Forge 1.7.10). One jar with everything.

Website with the install guide and the server guide: https://deciremnant.vercel.app/

Install

  • On 0.64.7 or 0.64.8: click Update in the main menu, wait for "Complete!", then Quit game (start the game again from your launcher) or Later (the update is put in place when you close the game).
  • On 0.59.0 to 0.64.6, or a new install: replace mods/Decimation.jar with this Decimation.jar (remove any deciworldgen-*.jar too). The updater of those versions cannot find its own jar, so install by hand once.

Changes since 0.64.8

This release is about performance and stability.

Smoother play

  • New city land generates about twice as fast. The short freezes when you walk or fly into a new part of a city are about half as long: the longest we measured fell from about 470 to about 210 milliseconds. Land that was already generated stays as it is.
  • NPCs are drawn much faster: each look is drawn from one picture instead of seven layers, and guns and gear are drawn in one go. Armed NPCs take about half the drawing time, which helps most in fights and camps.
  • Safezones and crowds: traders, guards, bandits and mechs no longer search for targets every tick, and NPCs no longer check every loaded creature every tick.
  • The intro screen no longer keeps a processor core busy for the whole session, and the game stopped checking BoehMod's closed version server.
  • Radios and other looping prop sounds stop when you are out of hearing (at most 6 play at once).
  • Blood splats stop moving once they land, and infected no longer plan wander paths nobody walks.
  • Decimation's melee weapons, throwables and name tags no longer cause thousands of OpenGL "Stack overflow" errors in a session.
  • With the intro, sound and version check fixes above, the frame rate held steady in our long play sessions instead of falling minute by minute.

Fixes

  • A muzzle flash no longer lights up every mob drawn after the shooter.
  • NPCs with night vision goggles no longer have a dark vest and backpack, and their gear now covers their hair and beard.
  • Scopes work with OptiFine: the gun stays visible while aiming, and a scope at the hip shows a plain lens, not a frozen picture.
  • The hand holding a gun shows your own skin, not Steve's.
  • Your last grenade, molotov or smoke grenade no longer stays in your hand forever.
  • Corpses open with a right click while you hold a gun.
  • Place names show again after you rejoin a world.
  • No crash of the HUD when a world is joined without passing Decimation's menu.
  • /gamerule doMobSpawning false also stops our NPC spawners.
  • The update screen's bar fills to the end.
  • The Continue button's tooltip reads "Last played: (your world)".

  • On 0.59.0 to 0.64.6, or a new install: replace mods/Decimation.jar with this Decimation.jar (remove any deciworldgen-*.jar too). The updater of those versions cannot find its own jar, so install by hand once.

Changes since 0.64.7

  • The update screen reads like Decimation's own did: the version and its size, "Downloading: 33%" then "Complete!", and the downloaded size before the total.

0.64.7 17 October 2026 · pre-release

Singleplayer fixes and world generation for Decimation (Forge 1.7.10). One jar with everything.

Website with the install guide and the server guide: https://deciremnant.vercel.app/

Install (once)

  1. Remove any deciworldgen-*.jar from your instance's mods/ folder.
  2. Replace mods/Decimation.jar with this Decimation.jar.
  3. Start the game.

On 0.59.0 to 0.64.6: install this version by hand once. The in-game updater of those versions cannot find its own jar and stops with "this game does not run from a jar (dev folder)". From 0.64.7 on, the menu's Update button works: it downloads the next version, then Quit game (start the game again from your launcher) or Later (the update is put in place when you close the game).

Changes since 0.64.6

  • The in-game update finds the game's own jar, so updating from the menu works from now on.
  • The update runs on Decimation's own update screen: progress bar, file size, "DO NOT CLOSE YOUR GAME!" while it downloads, then Quit game or Later.
  • Our DeciRemnant logo in the menus, where the DECIMATION lettering was.
  • Pop up messages carry the title DeciRemnant, and the Server Status page's Website row checks our website.

0.64.6 17 October 2026 · pre-release

Singleplayer fixes and world generation for Decimation (Forge 1.7.10). One jar with everything.

Website with the install guide and the server guide: https://deciremnant.vercel.app/

Install (once)

  1. Remove any deciworldgen-*.jar from your instance's mods/ folder.
  2. Replace mods/Decimation.jar with this Decimation.jar.
  3. Start the game.

Already on 0.59.0 or newer: the menu button says Update. Click it, wait for the download, then choose Quit game (start the game again from your launcher) or Later (the update is put in place when you close the game).

Create a new world with the world type "Decimation" to get the newest cities: city sizes, airports, wasteland gates and refuges only appear in worlds made with this version.

Changes since 0.59.0

  • Cities of 4 to 64 districts, with refuges spread through the big ones (new worlds).
  • Wasteland gates in the inner fence: most are shut (wire and landmines, steel, a bus, HESCO), a few are broken open; T junctions where city streets end.
  • Military airports in wasteland cities: runway, taxiway, hangars, tower, fighters, revetments, armory, fire station, radar and a garrison (new worlds).
  • NPC tracers stop where the shot stopped, so they no longer fly through buildings.
  • No more connection attempts to BoehMod's closed network (a background thread leaked every 15 seconds).
  • The world clock's day counter keeps counting after Decimation's daily time reset.
  • The update check survives GitHub's rate limit.
  • Main menu: our news panels (GitHub, Updates, Website, Coming soon), real scenes of our world as the background, a new one every 7 seconds, our name and version, Website and GitHub links, a Continue button that opens the world you played last.
  • Server pages: Bukovka and Chernarus are coming soon, Players Online says coming soon, Server Status lists Global Server, Community Server and Download (offline for now), and My Supporter is now Early access.
  • Bloaters, hulks, mechs and frails that Decimation swaps in while a chunk loads no longer move and attack at double speed (they were added to the world twice).
  • Airport and bunker garrisons: every post gets its guard, also posts far from where you arrive, and guards stay at their posts and walk back to them after a fight.
  • The wasteland checkpoint gate closed with HESCO can no longer be climbed over.
