- Create a negative review on Steam BEFORE you get a refund.
- Add negative reviews for previous Warner Bros titles. Hit them in the catalog, not just with this title.
- Get a refund.
- Report the product on Steam (flag icon next to the Share and Embed buttons on the page). Report it as "Broken"
- If you bought from a non-Steam source (such as GMG), ask for a refund anyway. It might feel like you're wasting your time, but GMG isn't ever going to create refunds unless there's demand. And trust me, with enough customer support tickets, GMG will put pressure on Warner Bros.
- Report Warner Brothers to the Better Business Bureau.
- If you know anyone in the video game press, ask them to cease all coverage of Arkham Knight until the PC issues are resolved.
- Don't let threads in gaming communities fail
- Use social media for public shaming of Warner Brothers. Commit to some reasonable schedule. Don't harass or threaten them, simply state your disappointment every few days.
Alternatively, you could try this:
- Get a refund and move on with your life.
