Some sort of first-aid/surgery kit that gives you your lost limbs back and restores the 'gibwounds' to 0.

Has this been done already? It's really hard to find anything with the search function.

In CaveCricket48's Medical Supplies mod.
Enjoy.

Post for bump, so it's a little more obvious there's new content.

Unfortunately, the previous assigned mod does not work too well.
When one uses the repair kit/script on a brain-character/(Main single-player character), the game will just delete it and place a new one, the player effectively failing the campaign.

Is there some other way, such as passive regeneration of wounds (Non-aesthetic) that can help the player achieve the... somewhat impossible campaign set out for him?

Without making him look like a tomato tree (Yes, there's a tree called like that before you ask) from all the wounds he's had to endure, or a simple way of just making the char have a gibwoundlimit of infinite proportions, seeing that is just plain cheating.

No, as of b23 wounds cannot be removed without deleting and replacing the actor.

Dang, that sucks.

Any way to block the game from kicking the player out of a singleplayer match because of this though?
Maybe a placeholder brain... eventhough the player is forced to play a single character?

Well, deleting and replacing the actor wouldn't really be out of place for removing wounds, as you can just give it the same health as the previous actor.

I'm not certain, but placing a temporary brain somewhere off the map while doing the replacing may fix it. Not sure if any brain dying causes a loss or if only one is necessary to be living.

That really depends on if it's skirmish or a campaign coded to check if that brain dies.

Like I said, it's a campaign.

I'll see what I can do though...
