Crysis 3 is the third (well, technically fourth) in a series of first-person action games that mix stealthy sneaking with huge explosions, all draped across lush, exquisitely rendered environments. The result has historically been something a bit smarter and more open-ended than, say, Call of Duty or Medal of Honor.
The series isn't really known for its winning personality. The games don't get by on their stories, or their characters, or their lore. They're not even really all that widely regarded for their gameplay or design. They're known, first and foremost, for their sweet, sweet tech. They are about using your suit's powers to stalk and kill dudes. Sometimes you hunt human dudes, and sometimes you hunt alien dudes. This has traditionally been a good amount of fun, because of one crucial balancing feature of the nanosuit—it runs out of energy rather quickly, and you can't stay invisible or bullet-proof for too long before you'll have to pause and recharge.
But every time Crysis games get away from that core routine, things become significantly less enjoyable. I've always had a soft spot for the series. Crysis 3, unfortunately, spends most of its time lost in the weeds. There's plenty of hunting, but it's sporadic, and changes made to the formula combine with dodgy AI and odd level-design to make the whole thing feel uncomfortable and ungainly.
