Campaign Description

Five Nights TD 2 is a Roblox tower defense game inspired by the Five Nights at Freddy’s universe. We programmed approximately 90% of the game ourselves, building all core systems, mechanics, and optimizations. The game launched with a peak of 40,000 concurrent users on release and quickly grew into a million-dollar title on the Roblox platform. Our goal was to create a high-performance, replayable tower defense experience. We built modular systems for enemy waves, tower logic, and game state management to allow for quick iteration and scalability. All programming was handled in-house, ensuring consistent design, balance, and optimization. Performance was critical. Enemy logic was processed in batches, visual effects ran client-side, and assets were pooled for efficiency. Towers used optimized targeting and cooldown systems, while enemy movement used waypoint interpolation for smooth gameplay. These measures allowed the game to handle tens of thousands of active players simultaneously without lag. Design choices drove engagement and revenue. Players unlocked towers and upgrades over time, waves included randomized elements to increase replayability, and difficulty scaled smoothly to retain players. The combination of high performance, deep progression, and fun gameplay led to strong player retention and monetization. Key figures: launch peak of 40,000 concurrent users, millions in revenue, and sustained daily active users well above industry averages for Roblox tower defense games. The game’s success demonstrates our ability to deliver high-quality, scalable games that perform under pressure and generate significant commercial returns.
