The absence of the light meter killed this game, you have no idea how hidden Sam is, the new meter in his back simply doesn't work, and combined with the weird lighting and bad AI, enemies can spot you pretty much randomly. Besides this, the majority of the levels are uninteresting, especially since most of them are in broad daylight, and not being seen in a place so well lit is completely ridiculous. (it doesn't help that Sam's model is always shining bright). Furthermore, in the JBA Headquarters sections, you're not able to run, the stealth mechanics are too simple to be fun, and going back and forth solving some minigames is just baffling.
