TMNT: Splintered Fate
Casey Jones & The Junkyard Jam

For the Casey Jones & the Junkyard DLC, I initialled led the design and implementation of Casey Jones, the first new playable character introduced since the game’s launch. Working in C++ within our proprietary engine, I developed his full combat kit and gameplay identity, emphasizing single-target precision and high-impact attacks to contrast the core cast’s broader combat styles. My work included prototyping and pitching multiple character kit iterations, designing character-specific upgrades, and adapting existing combat systems to support an additional playable hero in a game originally built for four. Throughout development, I focused on balancing Casey’s mechanics, refining his pacing and feedback, and ensuring his design expanded the game’s tactical depth while staying true to his brash, hard-hitting personality.

Alongside his development, I also designed and implemented the new Junkyard level, expanding the core campaign structure to include branching progression paths. This required integrating new path logic and balancing an entirely new environment that matched the existing third level’s difficulty curve while offering fresh gameplay dynamics. Within the Junkyard, I created and scripted key interactive elements and enemy encounters to complement the level’s industrial, chaotic atmosphere. I also designed and implemented the two new bosses: Gigi the mechanic and Head Of Security, The Junkinator, including their combat kits, core AI behaviors, and unique attack sequences. This work involved extending our gameplay scripting framework to support more complex, character-driven boss mechanics, bringing both variety and a memorable challenge to the new content.
