"Leon's body starts to writhe in pain as the Plaga parasite begins to grow."
This level introduces the threat of Plaga A. The Anonymous Letter is found at the start of the level. On the bridge, the Mask with Divots can be shot down. In a crate nearby is the notice to the villagers and "Closure of the Church".
