Set in a steampunk world that is increasingly being ravaged by volcanic eruptions, "Volcanoids" is a first-person survival game that blends exploration, base building, and combat. Players assume the role of members of a volcanic research team who must navigate a hostile environment filled with dangerous enemies known as the COGs, which are robotic creatures that have been ravaged by the volcanic activities. The game is characterized by its unique drill-ship mechanic, allowing players to delve into the earth to gather resources and construct a base while also fending off threats from the COGs above ground.
As players venture into the treacherous landscape, they can harness the volcanic energy to power their drills and improve their equipment. The procedurally generated world offers a variety of biomes and challenges, promoting exploration and resource management. Crafting and upgrading systems enable players to enhance their drilling capabilities and fortify their defenses. With cooperative multiplayer functionality, players can team up with friends to build and pilfer their way through this captivating world, making strategic decisions to survive the ever-changing environment and fend off mechanized foes, ultimately striving toward uncovering the mysteries behind the volcanic chaos plaguing their home.
