Spades (2)

[When Albert eventually realizes what is happening, the organism has taken control of his employees and servants.]

[The organism is too small for naked eyes to see, but when it spreads around, it travels through the dirt and can be passed from one human to another through physical contact.]

[The organism will invade a person's skin and control their minds.]

[Albert was desperate to destroy the organism before everyone was eliminated.]

[In his desperation, he used his authority to launch a missile into the whole country. It's not an explosive missile, but it's still the deadliest as it contains poisonous gas that was spread throughout the country. Albert extracted a special type of gas after discovering it can kill the organism within seconds.]

[When the missile was released and the poisonous gas was spread all over the country, all humans died. The other countries were also alerted by the epidemic and closed off the country from other nations.]
