Floating rocket launcher in Metropolis.

Handheld Scarab gun.

Tank that was supposed to blow up in Metropolis

 A strange launch caused by the joints in the Scarab's leg.

If you can get a vehicle on the top of a Scarab it will float. No clue why though. (The reason there is no gun in the first pic is because I was switching weapons.

Target tracking + Ledgendary + Sputnik + Marine with rocket =

Legs!!!

If you ride the pelican in Metropolis that drops off marines before you face the Scarab then you end up in a strange place.  The pelican is halfway in and halfway out of the ground and you can flip it if you're near it.  Knowing this I shoved a marine near it and pressed "X"...yea he was screwed.
