    Join the Black Mesa Research Facility with the Official Science Team ID of Dr. Colette Green

    This EpicIDs exclusive design replicates the ID badge carried by Dr. Colette Green, a key scientist and survivor of the Half-Life: Decay storyline. Styled with the clean, authoritative branding of Black Mesa, this non-personalized badge features Green's official photo, title, and credentials for a collectible cosplay prop with immersive accuracy.

    Along the bottom edge, you’ll notice a unique high-resolution cartridge-style visual effect — a striking element that blends retro-futurism with industrial utility. (Visual effect only — for immersive realism)

    Looking to expand your Science Team collection? EpicIDs also offers IDs for Gordon Freeman, Dr. Eli Vance, Dr. Isaac Kleiner, Dr. Gina Cross, Dr. Rosenberg, and Dr. Richard Keller — each with their own unique design and character-specific details.

    ⚠️ Science Hazard Advisory:
    This badge won’t get you through Sector D, won’t activate retinal scanners, and definitely won’t stop a tram. All clearance levels are for cosplay and display purposes only. Use with caution — especially near anomalous materials.


    • Standard ID Size — CR-80 card (3.375” × 2.125”), perfect for wallets or badge clips
    • Character-Specific — includes Dr. Colette Green’s canonical credentials
    • Double-Sided Print — full Black Mesa theming on both sides
    • High-Gloss PVC/PET Composite — durable, vibrant, and convention-ready
    • Exclusive Cartridge Styling — a printed visual detail for a unique in-universe look
    • Ideal for Half-Life cosplay, gaming conventions, displays, or team badge bundles
