Bio terminator

Bio Terminator is a ship weapon in Master of Orion.

Description
The Bio Terminator (B-T) pod is the most advanced and loathsome biochemical weapon ever devised. Its effects are best left to the imagination. Suffice to say that each B-T pod launched has chances of killing one Population Unit. The use of biological weapons is considered a transgression of the unwritten laws of civilized behavior, and does serious damage to your diplomatic standing with every race in the galaxy.
