Archean is a realistic, immersive multiplayer engineering sandbox and space sim. Featuring Earth 3 billion years in the past, in the Archean eon. You require an NVIDIA RTX gpu to play this game.
Players can construct a wide variety of vehicles and structures using a precise build system with small, resizable blocks ranging from 25 cm to 4 meters. The game requires carefully connecting components using intricate networks of cables, pipes, and other systems for power, data, and fluid transfer, creating a more realistic and involved building process compared to other sandbox games.
The game accurately models aerodynamics, buoyancy, orbital mechanics, and other physical systems, allowing players to design and build vehicles that behave realistically. Many reviewers praise the depth and accuracy of the physics simulation, stating it surpasses other engineering-focused games like Space Engineers.
Players can use the game's custom "XenonCode" language or a node-based visual programming system to script the behavior of their creations. This enables a high degree of customization and automation, with players able to program everything from simple control systems to complex logic and artificial intelligence.
The game features a procedurally generated, full-scale representation of the Earth and Moon, accurately modeled down to 1 mm precision. This massive, open world environment encourages players to explore and overcome the challenges of traversing the terrain, accessing resources, and reaching new destinations, such as the Moon.
The game supports both solo and multiplayer gameplay, with dedicated servers allowing players to collaborate and share their engineering creations. Reviewers highlight the smooth and stable multiplayer experience, which enables seamless interaction and cooperative building.
The game utilizes a fully ray-traced graphics engine, which provides realistic lighting, reflections, and refractions. While this approach requires an NVIDIA RTX graphics card, many players praise the visual quality and immersion it creates, especially in the game's realistic space and atmospheric environments.
Despite the sandbox nature, the game provides players with progression and challenge through its "Adventure Mode." In this mode, players must gather resources, craft equipment, and build their way up to more advanced technologies and the ultimate goal of reaching the Moon. The early game is described as a "grind," but the sense of accomplishment in overcoming these obstacles is a key part of the gameplay experience.
