LawBreakers

Launched Aug 8, 2017 to decent reviews but commercial DOA, with Steam peaks under 100 players within months. Boss Key fought for roughly nine months: balance patches (v1.3 role limits, Promenade night mode), the All-Star Update adding ranked play and new maps, a 2018 feature roadmap, free weekends (Sept 2017, Nov 2017), and price cuts down to $14.99. In April 2018 Bleszinski publicly acknowledged the failure; in May Boss Key closed after pivoting to the flop Radical Heights. Publisher Nexon then kept servers up, made the game free on Steam in June 2018, disabled all purchases, gave three months' notice, and shut down Sept 14, 2018 — but accepted no refund requests. Critically, the developer chose a new battle royale over its existing players, which is the abandonment that counts.

• Boss Key shipped meaningful post-launch support for ~9 months: balance patches, ranked mode, new maps, and a 2018 roadmap — the strongest Patch Speed in this batch.
• Player-count rescue attempts (free weekends, 25% and 50% price cuts, referral free-copy promotions) showed real responsiveness to the empty-lobby crisis, even though none of them worked.
• Attribution is the story: the developer (Boss Key) abandoned LawBreakers to chase Radical Heights and then closed; the publisher (Nexon) kept servers running, made it free, and delivered a clean three-month sunset — while explicitly declining refunds.
• Bleszinski was publicly candid about the failure ('It's a marathon. Not a sprint') and published a roadmap, but candor isn't follow-through: the roadmap died with the studio.
