describe

Better Chems has tweaked Chemistry crafting in Fallout 4 to give you and others a better drug-combination experience!

Chemistry crafting should be part of every gameplay, but most of the time, they don't seem worth using them, and if you use them once, you're instantly addicted and the positive effects run out before you even reach the enemy.

That's where Better Chems comes in to save the day! Reduce the chance of addiction and increase the duration of fun!

Also, do you know about Med-X? Something you never use? This mod makes it actually useful!

recommend

This mod also pairs well with Healing Stitches - No More Healing Limbs - F4SE, as you can now use Med-X to heal limbs and make your treatments more diverse!

Install & use Install: follow the bundled instructions

  1. Unzip the archive from playbuff and read the bundled readme / instructions first.
  2. There is no universal mod manager for this game: some mods replace game files directly, some go into a game-specific Mods folder, and some need a game-specific community loader or tool first — follow the bundled readme.
  3. Place the files exactly as the readme says; mods with listed dependencies need those installed too.
  4. Launch the game to confirm it loaded; some games require enabling mods in settings or an in-game mod menu.

Install locations vary a lot between games and mods — the bundled readme is the most reliable guide.
