with the shipwreck mission we need a smaller area as 3 attempts at it we havent found a crate, ship, or anything as we have to dive about 250m underwater with next to no light, this is a good idea yet its semi broken atm.
another suggestion would be better skins like more camo flauging ones, (i can learn how to make em if need be)
plane crashes that are lootable would also be nice (like drug shipments)
maybe a more diverse mining system (more minerals)
buildable bases is a big one that id like to see, there is a mod that i forgot the name to, but ik its possible but wed have to see
