Welcome to Ruins
One Small rural area surrounded by broken rock and some arch on top. Ruins is an abandon city that player rarely go there. It's located on the top left zone in the map. There are not much loots there and also when the safe zone is not in Ruins it make the rotation really hard because of the hill,lots of terrain that vehicle hard to drive on.
Down below will help you understand Ruins more:
Items mostly spawn on the ground under the arch. If rng is on your side you might find a good loots inside it.
If looting in Ruins and you don't get enough items. Walk straight out of ruins and you'll find a place call Church it's not far from ruins at all. These house will provide some more loot for you.
Personal Comment :
I used to drop into Ruins once and i barely get enough loots out of it. No helmet and no sight to play with.
