"Insectoid" doesn't appear in the
dictionary, but it probably should. "-oid" does, and I use "insectoid" in real life. I don't know about referring to them as insects in the immediately following sentence though...
Other than that the only things I noticed with the in-game description are:
"Consciousness" is spelled wrong in the Overmind description (missing the first 's')
The turret is referred to as "Machinegun Turret" in the menu and "Machine Gun Turret" in the description. Would be best to use one for both areas for consistency.
