Belt Zero: The Long Drift is an indie space idle simulation game set in a vast asteroid belt. Players begin stranded after a failed jump, with a wrecked ship and only a functional drill to start mining. The core experience revolves around repairing systems one by one using mined ore, gradually expanding from a single pod into a network of stations, colonies, and trade fleets that continue operating during offline periods.
Gameplay
The gameplay centers on continuous drilling into asteroids that yield chunks of varying quality, from common to flawless. A tractor beam allows manual collection, while collector drones handle automatic gathering across five tiers, functioning even when the game is closed. Drill depth progresses from D1 to D10, with deeper levels offering higher-value ore but introducing greater risks and heat management through thermal settings like normal, boost, and overdrive.
Asteroids vary across ten types, each with unique properties such as gas pockets or time-limited opportunities for bonus yields. Repairs unlock features sequentially: selling cargo, travel between locations, drone deployment, and module additions. Seventeen upgrade lines, each with ten tiers, visibly alter the ship from a basic miner to a larger cruiser with multiple drill heads and expanded storage. Power generation comes from sources like emergency reactors, fission cores, solar sails, plasma burners, and fusion cores, distributed across drilling, systems, cooling, and charging.
Research in a lab uses accumulated operating hours to unlock better equipment. Sectors beyond the initial Alpha Belt feature distinct stars and ores, discovered via scan probes that also enable mapping. Trade occurs through buoys with fluctuating prices driven by layered cycles, supported by contracts, freighter routes, escorts, and insurance. Refinement chains convert raw ore into materials, components, and assemblies for ship upgrades and structures.
Salvageable wrecks in each sector become modular factories with power grids and logistics networks. Research expeditions and megaprojects expand capabilities further. Colonies start with habitats and grow through building types across power, housing, agriculture, production, services, and infrastructure systems, supporting multiple goods and labor management. Factions with territories and relations allow trade, standing gains, treaties, and envoy missions, while anomalies and precursor relics provide additional progression paths. AI cores, ore mastery specializations, and a full jump reset system with meta upgrades support repeated runs, including New Game+ options.
Game Modes
The game operates as a singleplayer experience with no multiplayer elements. Core play focuses on idle progression that runs identically whether online or offline, with exact calculations for yields, production, and events during absence. A peaceful mode toggle removes raids and threats while preserving all other systems. Exploration involves launching probes to new sectors and managing trade waves across buoys. Combat elements appear optionally through warship classes for offensive actions against pirate targets, with risk assessments before engagement. The structure supports long-term empire building through stations, colonies, and faction interactions without time-limited events or forced decisions.
Progression and Exploration
Progression builds layer by layer from basic mining to complex logistics and diplomacy. Sectors introduce unique mechanics, such as lost chunks in certain fields or accelerated drill depth growth near black holes. Trade prices shift in predictable waves that players can monitor or forecast with scanners, encouraging storage strategies. Delivery contracts provide exclusive rewards, while wandering markets offer temporary high payouts. Colony economies scale from small outposts to populations in the millions, with visible orbital lights at night and interdependent production chains.
Deep drilling increases chances for twelve precursor relics across three sets, each granting permanent bonuses. Anomalies of eighteen varieties lead to choices with multiple outcomes. The FTL core repair enables jumps that reset ship upgrades but retain meta progress, achievements, and relics for faster subsequent runs. Five meta upgrade lines and slotted cards further customize each cycle.
Is It Worth Playing?
Belt Zero: The Long Drift suits players who enjoy idle simulation games with deep systems for mining, refinement, trade, and colony management. The exact offline progression, absence of energy systems or microtransactions, and buy-once model remove common frustrations. Verified mechanics like continuous drilling, visible ship evolution, faction relations, and optional combat provide substantial depth without dead ends or soft locks. Those seeking a singleplayer space empire builder that advances independently will find the step-by-step unlocking and long-term goals engaging. The early access state means ongoing development, but the core loop of repair, expansion, and multi-run progression stands complete for dedicated players.
