When browsing Steam, ever wonder if the publisher behind a game has a history of shutting down always-online titles and making them unplayable?

I built a userscript that checks the publisher on every store.steampowered.com page against the Stop Killing Games Dead Game List. If the publisher is known for killing games, you get a small amber banner above the purchase area with the specific reason.

Currently flags 16 publishers: Ubisoft, EA, Microsoft (Activision/Blizzard), Warner Bros, Bandai Namco, Sony, Square Enix, 2K, NCSoft, SEGA, Capcom, Rovio, Gameloft, NetEase, Nexon, Atari

Examples:

• Ubisoft → Shut down The Crew (2024), lawsuit in France
• EA → Anthem killed Jan 2026, unplayable
• Activision → Warzone Mobile killed Apr 2026
• Sony → Concord killed after 2 weeks

Design:

• Matches Steam’s native DRM warning styling (amber gradient)
• Dismissible, does not block purchases
• Links to per-publisher explainer docs with evidence
• No telemetry, open source
