Randy learned how to poison meat, to be honest this is a very specific skill, but nonetheless a fun little behavior.
Bait can now be used to reduce the health of enemies that eat it, or stumble over it.
The limitations are as follows:
1) You have to be hiding for enemies to take the bait if you are not hiding enemies will still try to attack you.
2) Once the bait item is picked up you have to press 'E' to place it on the ground.
3) Only one-piece of bait can be placed at a time. You can gather multiple pieces but only one can be present on the map.
There will also be a trailer video uploaded shortly after this post to help simplify the process.
