Large Roach Notes
These were normal roaches that lived in the sewers until becoming infected with the T-virus and growing to 40cm, or 8 times their normal size. Their natural hardiness has remained intact, helping their population to explode. They have a tendency to bite soft flesh on their prey and on humans, this tends to be the area around the cartoid artery.
There have been reports of attacks on humans where groups of the cockroaches have leapt to their victim's face, suffocating them with numbers. They fought with mutated rats for control of the sewers and won. Since then, they have demonstrated a tendency towards cannibalism.
