How One Game Studio Wasted Six Years Trying To Beat Grand Theft Auto

The collapse of Lightspeed LA’s ambitious project, Last Sentinel, serves as a cautionary tale regarding the challenges of replicating the success of established industry giants.

• Lightspeed LA, founded in 2020 by former Rockstar San Diego head Steve Martin and backed by Tencent, failed to deliver its open-world cyberpunk game 'Last Sentinel' after six years of development.
• The project was cancelled and 80 staff members were laid off following a failed 2026 playtest that resulted in an unmet ultimatum from Tencent.
• The studio struggled to bridge the production gap between its team of a few hundred employees and the 2,000-person workforce typically required to build high-fidelity, open-world titles like Grand Theft Auto.
