Once Human represents a significant entry in the mobile survival genre, developed by Exptional Global for Android platforms. The game positions itself as a comprehensive post-apocalyptic experience blending PvE combat, base building, and narrative elements within an open-world environment. Its current 2.0 update, dubbed 'Dreamveil,' introduces substantial content including the Endless Dream scenario and Dreamland Fantasia event, expanding the game's scope beyond traditional survival mechanics. The core gameplay revolves around survival mechanics including resource gathering, crafting, and base construction, distinguished by its relatively fast crafting system compared to genre standards. The newly implemented class system—featuring Chef, Gardener, and Beastmaster roles—provides specialized progression paths that significantly alter gameplay approaches. The deviation system functions as a pet companion feature with automated material collection, while the skill tree offers non-linear character development. The game's massive open world incorporates both horror elements and exploration incentives through its ongoing seasonal events and narrative content. User experience varies significantly across devices, with the interface designed for mobile accessibility but encountering technical limitations on certain hardware. The control scheme adapts survival game mechanics to touchscreen inputs effectively, though navigation and menu systems can become complex during extended play sessions. Real-world usage patterns suggest the game accommodates both short bursts of activity through its event systems and longer engagement periods through base management and exploration. The visual presentation maintains detailed environments and character models, though this contributes to the performance requirements. User feedback analysis reveals consistent praise for the game's genre-blending approach and content depth, though technical issues frequently surface in reviews. Quinn Ximon Camara's July 5, 2025 review notes render issues with premium content despite overall satisfaction, while Eric Bohenstengel's July 4, 2025 review highlights the streamlined crafting and base building systems. Multiple reviews including Aidynn Williams' July 4, 2025 feedback indicate persistent bug encounters affecting gameplay stability, particularly regarding screen orientation and rendering problems. Performance limitations appear device-dependent, as noted in Alex DeGroat's August 5, 2025 review regarding storage requirements. The game demonstrates notable strengths in content variety and genre innovation, successfully merging survival, crafting, and narrative elements within a mobile format. However, technical performance inconsistencies and device compatibility issues present significant limitations, particularly for users with mid-range hardware. The monetization approach through premium cosmetic packs, while avoiding pay-to-win mechanics, has encountered implementation issues according to user reports. Once Human ultimately serves as a compelling option for survival genre enthusiasts with capable devices, though performance optimization remains an area requiring development attention.
