What happens when a dummy is wounded?
The official Ragdoll Engine description by Ragdoll Co says that dummies have organs, bones, and blood. It links wounds and bleeding with several possible reactions: staggering, fainting, crawling, and bleeding out.
These reactions are useful things to watch for during the solo experience. However, the description does not establish that every dummy passes through them in the same order. It also does not explain which wound causes a particular reaction or how long bleeding lasts.
What the listing does not establish
There is no published damage table, blood-loss threshold, bandaging procedure, or organ-by-organ injury guide in the reviewed description. Claims about those details would require additional evidence from this exact game.
The developer separately states that R revives everyone. That is a revival instruction, not confirmation that R removes wounds or restores all damaged body parts.
