How can I earn the "...Without Bullets!" achievement?
Solution 1:
Your grappling hook can be used to pull down/apart any chaos objects, or sling explosive barrels into them. Alternatively, you can drive vehicles into things.
Solution 2:
The grappling hook is the easiest method and the easiest base to achieve this is Cima Leon: Silo. There are only a few chaos objects in the base and they are all easy enough to break with your hook.
The base is on the first island and the co-ordinates are N 40 41.334 E 5 43.546
