Additive Reconstructor

The Additive Reconstructor is a block in Mindustry introduced in Version 6.0. It is associated with producing or transforming units through in-game progression and research. The block received subsequent adjustments after its introduction, including new upgrade interactions and a change to its research prerequisites.

In Build 127 the Additive Reconstructor gained an explicit upgrade interaction: it can upgrade the unit Retusa into the unit Oxynoe. In Build 147 the research requirement for the Additive Reconstructor was changed so that players must capture the Biomass Synthesis Facility and then capture The Craters as part of the unlock progression. These version notes identify the Additive Reconstructor as a content piece tied to specific campaign or sector captures rather than only to a single linear tech tree node.

One persistent mechanical property recorded for the Additive Reconstructor is its inventory behavior: the block always holds double its input items. This doubling is enforced regardless of external modifications; the behavior remains the same even if the game is altered by mods or direct console changes. That deterministic inventory rule affects how players must supply inputs and plan logistics when using the block for conversions or upgrades that consume items from its storage.

Practical notes and interactions derived from available records:

• The block is part of content introduced in the 6.0 update and should be expected to appear in builds from that release onward.
• Use the Additive Reconstructor when following upgrade paths that include Retusa → Oxynoe, as that upgrade was explicitly enabled for this block in a post-launch patch.
• Research progression for the block requires capturing specific sector objectives following the Build 147 change; capture of the Biomass Synthesis Facility and later The Craters are part of unlocking it.
• Account for the block’s doubled-holding inventory when feeding it: supply planning should reflect that the block will effectively store twice the nominal input amount, which alters throughput and buffer sizing.
• Because the documented recipes/output listings for this block are not present in the available sources, consult in-game tooltips or the latest official game data for exact conversion recipes and output tiers.

The above summarizes the documented changes and a key mechanical trait for the Additive Reconstructor as recorded in available development and wiki notes. For exact recipes, in-game descriptions or an up-to-date game database should be referenced.
