Tetrative Reconstructor

The Tetrative Reconstructor is a Tier 5 unit production building in Mindustry notable for being the largest block in the game footprint-wise: it occupies a 9×9 tile area (81 tiles). Its name follows the reconstructors' mathematical naming convention — "tetrative" references tetration, repeated exponentiation — continuing the pattern established after the Additive Reconstructor (addition → multiplication → exponentiation). The block was introduced in Version 6.0 and received a health increase in Version 7.0 (from 3240 to 5830). It can upgrade the unit Aegires into Navanax.

Production behavior follows the usual reconstructors' rule for input storage: instead of the fixed 2000-item storage cap used by non-unit-producing blocks, the Tetrative Reconstructor holds a maximum of double the required input items for its processes. Output consists exclusively of Tier 5 units and Tier 4 inputs feed into its upgrade chain; exact recipes are determined in-game and by the unit types selected.

Operating a Tetrative Reconstructor demands a very high and steady throughput of both items and liquids. Even with overdrive enabled, manufacturing Tier 5 units is time-consuming and resource-intensive; setting up the required infrastructure can be difficult during early campaign defense. Typical sustained input rates (assuming equal overdrive across production chain) require upstream production roughly equivalent to: one Silicon Crucible producing ~5.3 items/s, three Plastanium Compressors at ~3 items/s each, three Surge Smelters at ~2.4 items/s each, three Phase Weavers at ~1.5 items/s each, and around fifteen Cryofluid Mixers to supply cryofluid demand. The cryofluid demand is especially large and cannot be practically delivered by Pulse Ducts alone; high-throughput liquid handling is necessary.

• The Tetrative Reconstructor is the largest single block in Mindustry by size (9×9, 81 tiles).
• Named for tetration; continues the mathematical naming progression of reconstructors.
• Introduced in Version 6.0; health buffed in Version 7.0 to 5830.
• Can upgrade Aegires into Navanax.
• Stores up to double the required input items (unit-production storage rule), not a universal 2000-item cap.
• Extremely high resource and liquid throughput required; full production lines of specialized buildings are necessary to keep it fed.
• Cryofluid throughput cannot be handled well by Pulse Ducts alone; use Liquid Junctions, Liquid Containers, and Liquid Tanks to share and buffer cryofluid with near-infinite effective throughput. Running solely from stored cryofluid requires a very large capacity — roughly 24 full Liquid Tanks to upgrade a single unit from stored cryofluid.
