# Sybreed - Doomsday Party (Experimental Infusion Audio Replacer)

### Description
Super Earth’s Ministry of Science has upgraded the **Experimental Infusion** combat stim with high-grade cybernetic industrial metal. Whenever you inject a stim while running the Experimental Infusion booster, the vanilla ringing and synth sound effects are replaced with **"Doomsday Party"** by **Sybreed**—fueling your adrenaline-boosted sprint through Automaton crossfire and Terminid swarms.

Created by **Desiderium**.

### Main Features
* **High-Octane Experimental Infusion Audio:** Replaces the Experimental Infusion booster sound effect with *Sybreed - Doomsday Party* (48kHz stereo Wwise Vorbis).
* **Remastered Audio Mix:** Uses unattenuated (0 dB) playback curves so the music cuts clearly through heavy combat and explosions without overpowering core game cues.
* **Vanilla Injection SFX Preserved:** Keeps the satisfying mechanical needle stab, hiss, and exhale sound effects intact upon injection.
* **Two Distinct Versions Available:**
* **Version 1 (Autotune Intro):** Includes the full ~22-second sequence starting with the iconic vocal autotune intro before dropping into the main riff.
* **Version 2 (No Intro):** A ~19-second cut that skips the intro and drops immediately into the heavy riff the moment the needle hits.

### Requirements
* **Base Game:** *Helldivers 2*
* **In-Game Booster:** The **Experimental Infusion** booster (from the *Viper Commandos* Warbond) must be equipped by you or a squadmate in the mission loadout for the audio to trigger on stim use.
* **Mod Manager (Recommended):** [HD2 Arsenal](https://www.nexusmods.com/helldivers2) or Helldivers 2 Mod Manager.
