My dad (also a Transformers fan) walked in to me clicking the anvil button repeatedly, and was very disturbed that I was cackling over this
On another note, I have learned you can game the system by repeatedly spawning in numerous of the same 3D items, and resetting Prowl a ton of times after they've been spawned. Apparently, the hitboxes will interact even if you didn't actually throw the object at him, and you can just disturb the ones you haven't interacted with to make Prowl hit them all again.
11/10 game, would recommend.
