A third-person multiplayer action game, Omegalodon feels mildly like a tribute to the monster movies of yore. In this game, players can elect to play as representatives of the human species or as a 100-foot shark monster and his entourage of healers. Choose whatever you will. The objective of the game is pretty straightforward. To win as a member of the monstrous Green team (who comprise of the Omegalodon and his Enviros), you're going to help ensure that a certain nuclear containment facility explodes before the timer ends. As the humans, well, it's your job to stop the invasion. Simple, eh?
There are a fair number of vehicles to utilize, environments to obliterate and voice acting to relish
