If the player has chosen close combat equipment as one of their starting perks, then they will receive the following weapons at the beginning of the game: On failure, 14 points are spent on evolving a Pustule that participated in last combat if possible, otherwise 10 points are spent on spawning a Pustule. At 15 or above, a Destroyer that participated in last combat has a chance to evolve into a Plague lord, up to 100% at 18. On failure, 10 points are spent on spawning a Pustule instead. At 11 or above, a Pustule that participated in last combat has a chance to evolve into a Destroyer, up to 100% at 14. At 8 or above, a Pustule may be generated, it is guaranteed at 10. These points are banked until they're successfully used.

Xenoplague is unique in that its units cannot be normally built. After Xenoplague outbeaks turned some planets into throbbing bio-hells, further development was forbidden. This process resulted in an exponentially-growing force of nightmarish monsters named the Xenoplague. The parasite injected cells into hosts that consumed the biomatter around them using a corrosive bile.
The bio weapon they designed was highly aggressive. The Star Union used it both to improve the physiology of their elite soldiers and to infect enemies with horrifying mutations. It was a parasite capable of incorporating the DNA of its host into its own body, collecting traits from thousands of species over its lifetime. Centuries ago, an expedition discovered an alien creature that came to be known as the Alpha Strain.
