Gengineering is the art and science of manipulating hereditary material to modify organisms or even to create entirely new organisms. Traditionalists restrict the term to manipulations of the hereditary material of biological organisms, and sometimes just to Terragen organisms. Others apply the term to any technology that involves altering the code of neumann-capable devices, regardless of substrate. Popular usage tends to lean in the direction of the more traditionalist sense of the word, but this varies by context.
Terragen gengineering began with the realization that the primary code for hereditary material in Old Earth's biota is carried in DNA, and with the evolution of techniques to understand and edit that code. The term "gengineering" emerged during the Information age, at about the time when results actually became reliable enough to merit the term "engineering". In humans and other eukaryotic organisms this meant an ability to manipulate epigenetic effects, to alter not only nuclear DNA but the DNA of mitochondria and chloroplasts, and a recognition of additional structures and substances involved in heredity. Understanding these systems and their interactions and long term effects was to remain a challenge for centuries, as it still is for neophytes in the field today, but essential techniques were well established by the dawn of the Interplanetary age, and helped account for the rise of powers like the Gengineer Republic early in the pre-Technocalypse era. By then biological vat-based and cell culture based industries were essential components of the economy, splice and tweak organisms had become ubiquitous, and the first provolved clades had emerged. Gengineering and gengineered organisms have been foundational to and pervasive in Terragen civilization ever since. In the case of major Sephirotic powers such as the Zoeific Biopolity, interstellar organizations such as the Institute for Primate Provolution, or movements such as Pan-Sophontism, gengineering is important in an ideological as well as in a practical sense. The vast majority of existing bionts today, sophont and otherwise, are products of gengineering, either in whole or in part.

Bamagliders are explosive filigliders. These range in composition. Some are merely normal filigliders with carbonated or nitrous oxide injected filling. Others are non-edible filigliders that produce a small fire-cracker explosion at a safe distance from the appropriate pheromone source. Additionally, like the poisiglider, there are some maliciously designed bamagliders that explode with damaging force in close proximity to a particular pheromone source.

- Biowar - Text by M. Alan Kazlev
An organic warship, a sentient, self-contained, evolutionary, self-replicating superbright bio-autowar. Like autowars, biowars can form long-lived populations and make regions of space hazardous long after the original conflict is over.
- Biowar Egg - Text by Anders Sandberg
Unlike autowars, that reproduce by mechanically constructing an identical ship, biowars replicate organically. Biowar eggs can drift, passive and undetected, for centuries before being activated through the proximity of raw resources. Because some types of biowar may lay literally millions of eggs, it becomes extremely difficult to control their populations. The illustration shows hatching biowar eggs in the asteroid belts of the Triumphant Fate system, 5985. The standard Biovirate template involved a plant-like growth on carbonaceous asteroids, feeding a spherical "egg" that eventually detaches and frees itself from the cocooning growth. Eggs hatch after 10-20 months, birthing a biowar. The shell contains secondary seeds, which will drift to other asteroids to plant the growth.

In the latter half of the Information Age and even well into the early Interplanetary Age, genetic engineering corporations had a problem: they had to find mothers to carry the genetically altered children they produced.
