This trick, as reported by Eurogamer, involves landing your own ornithopter on another player’s and then placing a thumper in the ground to summon Shai-Hulud, the ever-hungry sandworms that roam all over.

This works because, while vehicles can no longer damage people by ramming into them, they can still block other vehicles. This was apparently a common tactic out in the Deep Desert, where it was annoying but relatively fair game considering that’s the PvP zone, but now it’s popular in Hagga Basin, too.
