All you need to do is join a multiplayer server or create a single-player game on the new map. As soon as it loads, you'll get the achievement.

This achievement is also very easy to obtain. You just have to find a camp and use a shovel to dig in a spot like the one shown in the image below. The drop is random. When you get a worm, eat it and you will obtain the achievement.

This achievement requires a little more work. We need to obtain three items:

Motor oil can be easily found on farms, military bases, and construction sites.



Cable reel can also be easily found in construction sites or military zones.



And finally, we need the concrete bag. This is more difficult to find, but it can appear in construction areas and even in the dead zone. It's much easier to find them there.



Once you have all the items, we must go to Pinehurst, specifically to this location:



We start by putting motor oil in the generator:



Then we need to quickly go and repair the cables on the floor below using the cable reel:



Finally, we must climb as quickly as possible to where we find the mixer to place the concrete bag, and thus we will obtain the achievement:

This is probably the most challenging achievement of all. To get it, we must collect all these pieces and create the Widowmaker. I got the pieces in the Deadzone and high tier zones after many attempts, but it's not impossible. If the recipe doesn't appear, don't worry! When you get the first piece, you'll be able to see it.

Finally, we have this achievement. All we need is a weapon that is not suppressed and a silencer kit. When the recipe appears, we create the suppressed weapon and we will have the achievement. The kit can be easily found in military zones, where we can also find weapon repair kits.

That’s all you need to know to unlock every achievement in the Limestone map without using cheats. While some of them are quick and simple, others require a bit more patience and exploration—but with this guide, you should be able to complete them all and move one step closer to 100% completion in Unturned.

I hope this guide was helpful and saved you some time while hunting achievements. If it did, feel free to leave a thumbs up or a comment—it really motivates me to keep creating more guides like this for the community. Good luck, and enjoy exploring Limestone!
