My pleasure, in the meantime I managed to edit my scenario, so here goes. There are a total of 6 traders and they are just on the edge of the towns, close to small buildings usually surrounded by walls/fences. They should stand in the courtyard and not move around.

SPOILER --- TRADERS LOCATIONS
East of Athira
North of Pyrgos
South of Kavala
North of Aggelochori
West of Paros
North East of Syrta
END OF SPOILER ---

Enjoy everyone ! And if you need more precise info, I will send you screenshots in dm

Thank you, I appreciate you taking the time to reply as it gives me something to go off when finding them

Hey, it's been a long time since I played and I changed computers so I can't edit my scenario anymore. I believe I put 5 traders max on the map and they were all in industrial sites just outside of towns. You want to look for storage like sites on a main road near the towns, if my memory serves. Best of luck !

I haven't come across any traders yet in the game, I have tried docks, army bases, farms, some towns. Where is the best place to find one please?

Hello ! No, my knowledge in modding and scenario making doesn't allow me to make such things haha, but maybe there is a hidden mechanic in base Ravage that I don't know about for long-term gameplay. On my end tho, no endgame mechanic included. Have fun !

If you've been SENT, that presupposes that you are supposed to report back to whoever sent you.

Does that imply there's a way off the island if you can live long enough to find it?

Yes loot chances are much higher (you may even have too much food haha)

What about loot rates/chances? Are they higher or lower than vanilla ravage? I really hated vanilla loot system where you find 1 can of food every 4 hours without any way to open it and I constantly die because of it.

There are runners onlyin the main towns centres. In the countryside or in small villages there are only walkers.

What kind of zombies are in this scenario? Walkers only or runners too?
