When a horde of 2,000 Infected begin overrun the facility at The Military Hospital, Willimas is one of the many soldiers to station themselves at the fence where the infected are piling up. Willimas and the others soldiers unload their ammunition at the infected, however there are too many and The Infected break through. Willimas is the first to be bitten by an infected. The infected latches on to his neck, however Willimas pushes him off and puts him down. As Willimas is bleeding, he applies pressure to his neck and runs to talk briefly with the crew of a helicopter. We don't hear what was said but Willimas then runs head first into the helicopter tail rotor, killing himself and also preventing himself from turning. It is unknown if Willimas was intending to run to the medical bay inside the facility, or went into the rotor on purpose.
