There's a Pig build where the rules of DBD completely take a 180 and the entire game turns into a different thing entirely.

Knockout, Third Seal, Thrill of the Hunt and Franklins. With Last Will and Face Masks.

Slugging becomes more effective and time consuming for Survivors than hooking. People will sometimes go 2+ minutes on the floor without getting up. Because the other Survivors can't see them (Third Seal+Knockout) and they can't see the other Survivors (Face Mask).

Also, when the slugs finally get up after a century on the floor. They usually have active traps, an item somewhere on the ground and they desperately want the hex totem cleansed.

The game turns into a frantic slug hunt, totem hunt, item hunt and jigsaw box hunt. Most of the kills are death on first hook, bleed out on the ground, head pops or DCs. It's very entertaining to watch red rank players slowly lose their minds playing against this.
