Chinese studio YinHu Games opened the Steam store page for its in-development mech action game Iron Grave: Planet 9. The Vampire-Survivors-like title has players pilot mechs, fight hordes, and evolve machines across a future 9th planet. A demo is scheduled for November 1, 2026. Japanese language support is planned.
Iron Grave: Planet 9 is set on the solar system's 9th planet, over 100 years in the future. Players take on the role of mech pilots, fighting, exploring, and working with allies to uncover the past of Earth's civilization and the secrets of the planet.
Each mech type has its own evolution tree. Weapons range from rifles, heavy cannons, and light blades to positron cannons and railguns, and combinations alter performance and combat style. The game also includes chipset and wingman systems: chips installed into mechs boost performance, while wingmen can be deployed to fight alongside the player, with their growth routes and behavior patterns configurable. Formation and operation with wingmen are key to strategy.
Outside stages, players can upgrade industrial technology and analysis equipment, improve logistics support, and customize chipsets. The release date is undecided, but a demo arrives November 1, 2026. Japanese language support is planned.
