I did not create any textures and objects for this map, I just made it possible to pick up some elements on the map, added a collision, water with boats and some fun things to do, and elements to make it easier to climb. If you want, you can buy polygon packages and create similar maps. Good luck.
INFO : - This map was not created to finish it, it was created for a nice look and exploration. Honestly, it has no purpose. This is simply my first map and I learned how to use the Unity software (that's why I wrote that I put a lot of work in it). Maybe someday I'll try to do a big project that can be completed but I'm not an expert on the Unity software, there are a lot more talented people than me.
NOTE : - I know there is a sync issue in multiplayer, players cannot see any of the interactable objects,only where they spawned originally because map have too big size. I've exceeded the limit but map work perfectly if you are host. The only solution would be to reduce the map but I would have to delete many elements and I do not want to do that.
