Argos: Riders on the Storm was an online, co-op, immersive sim led by Warren Spector in a post-apocolyptic Paris. I built all the networked player movement systems including dodging, sliding, swimming, mantling, and a Zelda-style wall climb where the player can climb on any vertical surface. I also implemented the character’s animations using Unreal’s new Motion Matching system and developed our animal herd AI systems governing hunger/feeding, aggression, and sleeping using behavior trees and smart objects.
