Ankys can be used to farm unlimited metal, crystal obs etc. It takes 2 players. On in a quetz with a platform saddle and a ramp on the front. the other flying the quetz. Just scoop the anky with a player riding it and hit away. For some reason the ankys weight from the inventory doesn't count so the quetz can fly you across the map. If you fall off the quetz just scoops you back up!
