Raid Rush: Tower Defense TD is a mobile tower defense game with a roguelite twist, where players defend their fortress against waves of enemies by building, upgrading, and rearranging towers through randomized in-battle choices. Each run offers unique layouts thanks to procedurally generated maps and dynamic card selections, blending classic tower defense with survival gameplay, hero combat, and meta-progression.

As a Senior Game Designer, my role during the prototype phase covered multiple pillars of the project:

• Core Systems Design → Designed and balanced survival wave mechanics, tower placement and upgrade systems, fortress health management, and experience-driven card selection flow.

• Roguelite & Randomization Design → Defined the card-based upgrade and map randomization systems, ensuring replayability and emergent strategies across playthroughs.

• Combat Design → Designed hero abilities, player skills, and how they integrate into automated and active combat systems during survival battles

• Onboarding & FTUE Design → Helped craft the early player experience, guiding new users through tutorials.

• Cross-Disciplinary Collaboration → Worked closely with product, art, engineering, and UI/UX teams to align gameplay systems with visual design and technical feasibility.

Throughout the prototype phase, I focused on creating systems that offered both depth and unpredictability — ensuring each run felt fresh and rewarding, while laying the groundwork for long-term progression, competitive modes, and monetization systems before transitioning to my next project.
