Mid Game Guide: Progression & Common Walls

Mid game is the phase where your factory moves beyond basic belts and smelters: you must establish interplanetary logistics, scale complex chemical and electronic supply chains (silicon, processors, titanium), secure steady hydrogen/deuterium for fuel and fusion, and build defenses and a modest space fleet. Proper midgame planning prevents bottlenecks that block late-game matrices (Structure / Information / Gravity) and Dyson construction.

Goals and high-level priorities

  • Unlock and automate Structure Matrix production — this typically forces your first interplanetary logistics because Titanium (and Titanium Crudes) rarely spawn on the starter planet.
  • Establish dependable Hydrogen and Deuterium sources and conversion (Fractionators, Orbital Collectors, X‑ray cracking) to feed fuel rods and Gravity Matrix chains.
  • Scale Processor and Silicon supply lines; Processors become a pervasive bottleneck for Information Matrix and later Quantum Chip production.
  • Build Titanium supply (ore → ingot → titanium alloy) and Sulfuric Acid/Graphene lines for Titanium Alloy and Graphene needs.
  • Prepare midgame power: upgrade power generation (thermal, then Deuteron fusion) and deploy wireless chargers for Icarus.
  • Set up defenses (missile turrets, tethers to Signal Towers) and begin producing Corvettes for space combat where needed.

Research and tech progression

  • Target Mecha core upgrades (Core capacity/Mecha energy) to increase warp capability and endurance for interstellar trips; Mecha core Lv4 unlocks practical warping range.
  • Unlock Logistics Carrier Engine upgrades to speed up logistics vessels. Logistics Carrier Engine IV is required to use Space Warpers for interstellar logistics (vessels consume two Warpers per round trip).
  • Prioritize Structure Matrix research (yellow) early in midgame; it unlocks Interstellar Logistics System and Space Warpers which relieve many midgame supply problems.
  • Later, plan for Information Matrix (purple) and Gravity Matrix (green). Gravity Matrix production is hydrogen‑intensive and requires access to Deuterium and the Miniature Particle Collider or Fractionator networks.

Production chains and key components

Silicon and Processors

  • Processors are ubiquitous mid-to-late game components; each Processor consumes significant High Purity Silicon. Build dedicated silicon mining (on other planets if necessary) and smelting lines: producing High Purity Silicon from raw Silicon Ore by smelting is inefficient on starter world — import ores when possible.
  • When producing Information Matrices, particle broadband and processors are required; packet long craft times demand many Assemblers. Scale assembler capacity accordingly.

Titanium & Titanium Crystal / Alloy

  • Titanium Ore rarely exists on the starter planet; plan an interplanetary outpost for titanium mining and ingot smelting. Transporting ingots is more efficient than ore.
  • Titanium Crystal (used by Structure Matrix and Casimir Crystal) requires Organic Crystals plus Titanium Ingots. Organic Crystal production from Refined Oil is slow and power-hungry (chemical plants), so either create a large on-site refinery/chemical complex or locate mineral deposits that produce Organic Crystal directly.
  • Titanium Alloy is needed for Deuteron Fuel Rods, Logistics Station parts, and many midgame items. Sulfuric Acid (or a planet with sulfuric oceans) greatly simplifies titanium alloy and graphene production—if you find a suitable planet, establish your titanium alloy hub there.

Oil, Plastics, Sulfuric Acid, Organic Crystal

  • Crude oil → Refined Oil yields Hydrogen as a byproduct and feeds Plastic and Sulfuric Acid production. Plastic is required for Organic Crystals and Particle Broadband; Sulfuric Acid is needed for Graphene and Titanium Alloy.
  • Chemical Plants and Chemical Facilities have long craft times and large footprints; plan long, straight equatorial production lines for many units and provide substantial power.

Hydrogen, Deuterium, and Fuel Rods

  • Hydrogen is produced from oil refining and later harvested from Gas Giants (Orbital Collectors). Hydrogen demand fluctuates: Energy Matrices, Information Matrix chains, Graphene production, and Deuterium conversion all compete for it.
  • Deuterium is a specialized fuel required for Deuteron Fuel Rods (used in Mini Fusion Plants and as elite Mecha fuel) and Gravity Matrix recipes. Convert Hydrogen → Deuterium using Fractionators (energy‑efficient, especially when paired with high‑tier belts and buffering designs) or Miniature Particle Colliders (much higher energy cost per Deuterium).
    • Fractionator loops (with MK.III belts and buffering) are the midgame standard for energy‑efficient Deuterium.
  • Deuteron Fuel Rods burn in Mini Fusion Power Plants and are extremely energy dense; a single fusion plant consumes a rod every 40 seconds at full load. Fusion is compact and ideal for powering remote outposts and supporting logistics stations.

Super-Magnetic Rings & Conveyor Belts Mk.III

  • Super-Magnetic Rings are midgame components used by Conveyor Belt Mk.III and by Deuteron Fuel Rod production. Their production chain is complex and resource intensive; set up a dedicated production area when preparing large-scale midgame logistics.

Conveyors, Sorters, and Storages

  • Upgrade to Conveyor Belt Mk.III where throughput demands. Many midgame loops require MK.III (eg Fractionator chains).
  • Use Storage Tanks and Storage Mk.I as buffers when upstream produces faster than downstream consumes; buffers are crucial during interplanetary shipments and research spikes.
  • Place buffer storages before research lines to feed matrix labs steadily and accelerate research with proliferators if needed.

Logistics and interplanetary supply

  • Interstellar Logistics Station plus Logistics Vessels become essential to move titanium, silicon ore, and other planet‑specific resources. Logistics Vessels have base speed 600 m/s and gain massive increases from Logistics Carrier Engine upgrades; warp requires Carrier Engine IV and Space Warpers.
  • Warpers are expensive mid/late materials (better produced via Gravity Matrix at scale). Initially make small numbers from Graviton Lenses but shift to Gravity Matrix production for volume efficiency.
  • When establishing remote outposts, prefer producing heavy, low-volume items (ingots, fuel rods) locally and shipping them as processed goods to reduce trips.

Power management

  • Midgame power demand rises sharply: chemical plants, assemblers, fractionators and colliders consume large amounts. Combine thermal generation (burn fuels) with planned fusion plants for compact, high-output power.
  • Fusion requires steady Deuterium supply and significant midgame production of Super-Magnetic Rings and Titanium Alloy.
  • Wireless Power Towers are useful for charging Icarus in the field; they stack but draw substantial grid power—use them tactically for quick recharges.

Defense and space combat

  • Expect stronger Dark Fog responses and orbital attacks in midgame. Missile Turrets remain the primary automated planetary and orbital defense until higher turrets become available; use Signal Towers to relay long‑range target data so missile turrets can fire beyond their normal detection radius.
  • Produce midgame ammunition: Supersonic Missile Sets and Titanium Ammo Boxes require silicon and titanium—set up production before you need sustained defenses.
  • Corvettes are the first practical space combat ships. They are cheap to mass-produce and effective for distracting and chipping away at Hives and Relay Stations; build squadrons to protect logistics and outposts.

Practical layouts and scaling tips

  • Chemical production favors long, straight lines: chemical plants and assemblers in chains with side buffers and parallel power provisioning.
  • Dedicate separate zones for: (1) silicon/processor production, (2) oil/chemical/plastic/sulfuric acid, (3) titanium and alloy production, (4) hydrogen/deuterium production and fractionation, (5) warper and logistics component production.
  • Use storage and automatic piler loops to smooth intermittent production (e.g., Fractionator loops benefit from liquid buffers and automatic pilers).
  • Proliferators: applying Proliferator Mk.II to matrix production and research lines yields large gains in matrix throughput and research speed—use them when scaling up production of Structure/Information/Gravity matrices.

Common midgame bottlenecks and solutions

  • Silicon shortage: import Silicon Ore from other planets and prioritize Processor lines; scale High Purity Silicon smelters to meet Processor demand.
  • Hydrogen imbalance: if refining creates excess Refined Oil but hydrogen is insufficient for later needs, add Orbital Collectors on Gas Giants or use X‑ray cracking setups to convert surplus hydrocarbons and recover hydrogen.
  • Titanium access: establish a dedicated titanium planet base with smelters producing ingots and alloy, or find a Sulfuric Acid ocean world to simplify Alloy production.
  • Power shortfall: add Mini Fusion Power Plants once Deuteron Fuel Rod supply is stable; until then, expand thermal plants and stash fuel in storage buffers.

Mid game is the period of preparation: automate complex chemistries, secure interplanetary resource flows, and build the energy and defensive backbone that lets you unlock Information and Gravity Matrices and begin Dyson construction. Prioritize stable supply lines for Processors, Titanium, Hydrogen/Deuterium, and Warpers—solve these reliably and the late game becomes achievable.
