The Cannibals live in Lakeview Manor and are your main enemies in Lakeview Cabin IV.
They are an inbred family of cannibals with up to 13 members (exact amount depends on how many rooms spawn in the mansion). They are some of the biggest obstacles in the whole series, being unable to use doors but making up for that by occupying every room, often in pairs. The player usually lacks weapons to properly fight them early on and there aren't too many weapons to speaks of in the entire chapter. The best idea is to try not to trigger the alarm.
