Creepvine Samples are a Raw Material that can be harvested by using a Survival Knife on Creepvine plants. It can either be directly consumed, used in crafting recipes, or used to power a bioreactor. It takes up 4 slots in the player's inventory.
If too many Creepvine Samples are eaten at once, the PDA announces ''blood loss detected'' and the player's health will decrease.
In the Bioreactor, it produces 15 energy total over the course of 150 seconds.
