At Rebellion, I built one of the five core levels in Zombie Army Trilogy, a co-op survival shooter blending Left 4 Dead chaos with Call of Duty Zombies tension. Tasked with delivering a cinematic experience across PC, Xbox 360, PS3, and next-gen consoles, I used 3DS Max and Rebellion’s proprietary engine to craft a modular, atmospheric level built from a mix of bespoke design and repurposed Sniper Elite assets, balancing visual punch with tight, cross-platform performance.
