In the beginning, the character woke up from a leaked laboratory. After putting on the helmet, the helmet display showed the virus wandering in the room.


Since there are no weapons at the beginning, players can only rely on jumping to dodge dangerous viruses.


When the character finds a weapon, he obtains the ability to kill viruses. After he kills the big boss virus, he will receive the final reward, a vaccine.


The character passes through the dangerous contaminated area and delivers the vaccine to the safe area at the end of the passage, in order to save humanity.
