Details

Overview

Planet Forge is a space simulation game that puts you in control of a planet itself. Developed and published by Mr.

BLender, this Early Access title launched on October 29, 2026, and supports both single-player and multiplayer co-op, including LAN co-op. The core premise is simple yet ambitious: you guide a celestial body through space, using gravity to attract resources and grow your mass over time.

Highlights

Cosmic Evolution Chain: Absorb elements in space to increase your mass and seamlessly transform your celestial object—from a regular planet to a gas giant, and eventually into a star.
Own Gravity Mechanics: Increase your object's mass and density to strengthen its gravitational field. Powerful gravity lets you pull in surrounding gases, space dust, and other materials more effectively.
Multiplayer and Co-op: Play together with friends in co-op or LAN co-op modes, making the cosmic journey a shared experience.

Who It's For

Planet Forge is ideal for fans of space sims, god games, and immersive sims who enjoy a slower, more contemplative pace. If you like the idea of nurturing a planet from a rocky lump into a blazing star, or if you prefer cooperative sandbox experiences with friends, this Early Access title offers a unique twist on the genre.

The game is currently available in English and Russian, so players comfortable with those languages will find it accessible.
