Origin

The Green Flu in Left 4 Dead is a highly contagious virus that spreads rapidly among humans, turning them into aggressive and mutated zombies. It is believed to have originated from a mutated strain of rabies. On the other hand, the Blacklight Virus in Prototype is a man-made virus created by the military as a biological weapon. It was designed to enhance soldiers' abilities, but it ended up infecting the population of New York City.

Transmission

The Green Flu is primarily transmitted through bodily fluids, such as saliva and blood, making it easy for the virus to spread through bites and scratches from infected individuals. In contrast, the Blacklight Virus can be transmitted through physical contact with infected individuals or through consuming contaminated food or water. This makes the Blacklight Virus more versatile in terms of transmission methods.

Symptoms

Individuals infected with the Green Flu experience symptoms such as fever, coughing, and fatigue before eventually turning into zombies. The transformation process is relatively quick, with infected individuals becoming aggressive and violent within hours. On the other hand, individuals infected with the Blacklight Virus exhibit symptoms such as enhanced strength, agility, and shape-shifting abilities. The transformation process is gradual, allowing infected individuals to retain some level of control over their actions.

Effects on Host

Once infected with the Green Flu, individuals lose all sense of their former selves and become mindless zombies driven by a primal urge to attack and consume human flesh. They lose all cognitive functions and are no longer capable of rational thought. In contrast, individuals infected with the Blacklight Virus retain their memories and personality traits, albeit with a heightened sense of aggression and a desire for destruction. They are still able to think and strategize, making them more dangerous adversaries.

Combatting the Virus

In Left 4 Dead, survivors must rely on teamwork and resourcefulness to combat the Green Flu and navigate through hordes of infected zombies. They must scavenge for weapons and supplies while staying vigilant against the infected. In Prototype, the protagonist Alex Mercer must use his shape-shifting abilities and combat skills to take down infected individuals and military forces trying to contain the outbreak. He must also uncover the truth behind the Blacklight Virus and its origins.

Endgame

In Left 4 Dead, the ultimate goal for survivors is to reach a safe zone and escape the city overrun by the Green Flu. They must fight their way through various challenges and obstacles to reach safety. In Prototype, the endgame involves uncovering the conspiracy behind the Blacklight Virus and confronting those responsible for its creation. The protagonist must make difficult choices that will impact the fate of New York City and its inhabitants.
