Cult of the Lamb Sins of the Flesh: “Sex Update” Add Egg Hatching, Sin Mechanics

Sins of the Flesh, otherwise known as the "sex update," is finally out for Cult of the Lamb and brings tons of new features.

Today marks the release of what the community has playfully dubbed the “sex update” for Cult of the Lamb. With it comes a new weapon, new traits, and a whole lot more for the follower management aspect of the game.

Sins of the Flesh is one of the largest patches to Cult of the Lamb yet, and its notoriety proceeds it. We couldn’t breed and hatch our own followers in prior updates, and (luckily) the whole process is less salacious than some were speculating beforehand. But, it’s indeed the sex update, and your followers can canoodle each other — then lay eggs in the aftermath.

What’s Sin Got to do With It?

Aside from now being able to breed, followers are now also able to accumulate Sin. Sin can be used to build certain structures and can be used to upgrade the Temple. It comes with a new Doctrine specifically dedicated to Sin as well.

Sin can be accumulated in a few ways in the Cult of the Lamb Sins of the Flesh update. There are new Rituals to build up Sin and move it between followers, and two new buildings to generate Sin specifically. There are far more buildings added to this update than those to do with Sin, though. This is a big patch. Without further ado, let’s get to the full list of patch notes.

The “sex update” is more than worth reinstalling Cult of the Lamb for since it adds so much meat to what was already a content-heavy game. Sins of the Flesh is out now on all platforms, and it comes alongside the Sinful DLC Pack, filled with cosmetics. With all the new content and the fact that the game’s on sale right now on Steam, there’s been no better time to pick up this action roguelite.
