The Physics Engine behind GTA 4 and Red Dead Redemption - And the Game everyone forgot

In this video, I revisit the physics engine that helped define GTA 4, Red Dead Redemption 2, and one forgotten classic: Backbreaker. Before modern polish and scripted animations took over, Rockstar Games used the Euphoria physics engine to create something different - characters that reacted dynamically, stumbled, recovered, and felt genuinely alive. From GTA 4’s unpredictable ragdoll moments, to Red Dead’s weighty reactions, to the raw, unscripted tackles in Backbreaker, this was a time when physics didn’t just support the gameplay, but created it. This is a look back at Euphoria, the technology behind those moments… and why it still fascinates me today.
