Terrorists have unleashed giant cryptids on the nations of the world. Kaiju cryptids Bigfoot, The Mongolian Death Worm, Moth Man, The Loch Ness Monster and numerous others leave a trail of death and destruction across the globe. World leaders respond with the ROCS. Massive birds with cybernetic enhancements that share a neuro-link with the pilots who sync with them. The ROCs are the world’s only hope but will the pilots be able to understand their own hearts and minds in time to sync with the ROCS and battle the giant cryptids or will their faults and shortcomings as people be carried over into the kaiju themselves?

It has been six months since the terrorist Rol-Hama had captured the world’s cryptids. The madman transformed the cryptids into giant monsters and then unleashed them on the world. Sea monster attacks quickly shut down worldwide shipping. The world’s economies and vital infrastructures are falling apart. Essential supplies that keep the world functioning including food, medicine, and oil are unable to be delivered. In response the US government enacts Operation MEG (Monster Extermination Group). The plan consists of mutating two great white sharks to monstrous proportions. Now the fate of world is in the hands of Operation Megalodon.
