I also loved every alternate version of Knack. Stealth Knack is perhaps the best of the bunch, as it introduces one new button to play with: Triangle. You can instantly swap between a tiny crystal Knack that can run through lasers and a larger Knack that can fight enemies. When the game mixes the two elements together, you're constantly swapping between the two forms, staying on your toes. Unfortunately, the game restricts you to Vanilla Knack most of the time. What Knack lacks as a game, it cannot make up for with next-gen spectacle. While Knack does push a lot of particles and polygons, it doesn't look especially next-gen. Knack's character model is incredibly complex, but the end result won't impress most casual onlookers. Even worse, the framerate can drop in scenes that involve destruction--disappointing given the relative visual simplicity of the title. The story is also a convoluted mess, going on for much too long. Even worse, its reliance on deus ex machinas is almost comical. The emotional manipulation that Cerny attempts through the story is a bit too brute-forced; Knack "dies" (and comes back) in the story no less than three times. BOOM video 15947 Knack may be the family-friendly option for PS4's launch, and it may adequately serve that function. The game supports two-player same-screen co-op, which does make the game experience a bit better due to your co-op partner's ability to respawn infinitely. However, it's clearly designed as a single-player game, with the camera exclusively focused on Knack, and the second character magically disappearing in the game's frequent cutscenes. In many ways, co-op feels like an afterthought rather than a fully-fleshed feature. Console launches typically feature two types of games. There's innovative genre-defining icons... and then there are the games that will be forgotten in a few months time. While Cerny may have defined a generation of platformers with Crash Bandicoot, Knack will be as fondly remembered as Genji: Days of the Blade is today. 
You humans are so useless
