A day after the failed attack the Chimera started to look for any survivors, forcing Mathison and the others to make their way into the subways. However, they discovered it was infested with Grims and other feral strains, with four soldiers killed as a result.
Six days later, Mathison became the sole survivor of his group. Trapped by the Chimera, he made his last stand in a sniper's nest in Washington Square. Armed with a sniper rifle with six remaining bullets, and one hand grenade, Mathison engaged the Chimera and was killed.
- Despite Mathison narrating that four soldiers died in the subway, corpses of five soldiers can be found instead.
- Mathison is the last member of Victor Company to be left alive.
