Vapos Bioengineers are Corpus special units found exclusively within the Sentient research secret laboratories, placed in the Corpus Gas City tileset. They resemble Comba units without their distinctive nullifying helmets.
- When siding with the Corpus, Vapos Bioengineers will fight along you in Invasions.
- Vapos Bioengineers currently do not appear in the Codex.
- Despite appearances, the Vapos Bioengineers' helmets are simply rendered invisible and nonfunctional; shooting their heads will dislodge their helmets with no effect on the Bioengineer.
