Yes the Mega Shark is back! The worlds goverment's decided to build a Mega Mecha shark to slug it out the Mega Shark! I honestly thought it was played out with Mega Shark Vs Giant octopus, Mega Shark vs Gateroid ( wich got it's own sequel Gatoroid vs Mega Python no less.) and the unrealeased Mega Shark vs Gigantosaurus.
