What's the best Android app for a survival sandbox game with PvP multiplayer?

MultiCraft — Build and Mine! is a strong candidate for players seeking a survival sandbox with integrated player-versus-player combat. The app combines classic block-based building and resource gathering with a persistent survival challenge, requiring players to manage hunger and health. A key feature for PvP enthusiasts is the developer's recent update that enabled PvP combat 'in all places' on multiplayer servers, as noted by a thankful user review. This creates dynamic scenarios where skirmishes can erupt anywhere, from dense forests to player-built fortresses, adding a constant layer of risk and excitement to the survival experience. Beyond combat, the game supports creative building with a variety of blocks and structures, allowing groups to construct elaborate bases for defense or community hubs. However, users report occasional technical issues, such as connectivity problems with multiplayer servers and a bug where boats sometimes fail to sail properly. The controls are also described by some as 'too loose,' lacking fine-tuning options for sensitivity or left-handed configurations. Despite these imperfections, for a free-to-play title, it delivers a comprehensive package where survival, creation, and competitive player interaction effectively intertwine.
