This is not Far Cry. The nanosuit your character wears in this spiritual successor turns you into a full-blown superhero, and it renders you near-unstoppable.
That means they've had to make your task exponentially harder to compensate, of course. This time you're taking on whole armies, fleets of vehicles, aliens the size of volcanoes and stranger things still. The resulting conflict is action of a higher order of magnitude. Every ten seconds something explodes, and a Crysis explosion is a hell of a thing to see.
