Casual 3D adventure games have grown significantly in popularity because of their accessibility, fluid controls, and visually engaging worlds. At the same time, suspense-driven multiplayer games have demonstrated strong replay value by incorporating hidden roles, uncertainty, and social tension. However, existing research shows limited attempts to merge both genres into a single seamless experience. This survey investigates the conceptualization of SwordFall, a hybrid 3D Swordigo-style casual multiplayer game. The paper analyzes existing adventure and suspense games, identifies challenges in merging their mechanics, reviews design and psychological factors, compares game structures, and proposes a technical roadmap. The outcome provides clear guidelines and a reference framework for developing immersive, casual, yet emotionally intense multiplayer 3D games.

This survey paper explored the design principles, gameplay structure, and technical challenges involved in creating SwordFall, a modern 3D reimagining of Swordigo combined with real-time multiplayer features. The goal was to understand how simple 2D adventure mechanics can be expanded into a fully 3D action–exploration experience while maintaining accessibility and supporting co-op and PvP gameplay modes. The study successfully addressed the core problem of transitioning a lightweight adventure formula into 3D by establishing a clear set of design pillars: exploration & platforming. The analysis identified essential elements such as traversal abilities, dungeon design, smooth combat flow, weapon upgrades, and skill progression systems. These components provide a strong foundation for delivering a modern yet casual gameplay experience. Overall, the survey provides a complete blueprint for the development of SwordFall, offering structured guidance for building 3D adventure games with smooth combat and multiplayer systems. This work also serves as a valuable reference for future developers aiming to create accessible, stylized, and performance-optimized 3D action-adventure games.
