It can only harvest meat and spoiled meat from bodies. Even if you’re harvesting Tek Dino’s. Everytime you attack a Dino, you gain some blood packs. It can fly backwards, hang on walls, has night vision which can only be activated at night. You can turn stealth only at night or if you’re on a wall, it’ll let you be stealth during the day. I haven’t found much use for the screech yet.
