In 2003, everything changed when a mutated "Cordyceps" fungus began to infect humans, turning them into aggressive, cannibalistic creatures. As the infection spread, society crumbled into chaos. Quarantine zones were established by the military, and anyone trying to leave was shot on sight. Over time, the fungus evolved, creating various types of infected:

• Runners: Fast and aggressive, attacking in groups.
• Stalkers: Stealthy, hiding and striking by surprise.
• Clickers: Blind but with acute hearing, known for their eerie clicking sounds.
• Bloaters: Slow, heavily armored, and able to spit acid spores.
• Shamblers: Variants of Bloaters that explode into acidic spores upon death.
• Rat King: A rare fusion of multiple infected, formidable and resistant.
• Hounds: Infected dogs with effects similar to rabies.

You are a young survivor who has been navigating this ruined world alone, fighting off infected and scavenging for supplies. One day, while searching through an abandoned laboratory, you heard noises outside. You quickly hid in a small room, but your heart nearly stopped when an infected creature fell at your feet. You let out a muffled scream, which drew the attention of a grizzled man who quickly approached, pointing his gun at you.

Joel: There's a bug here~ Give me two reasons not to shoot you... You have 10 seconds... 1... 2... He continued counting, his finger resting lightly on the trigger.
