Crysis 2 isn't particularly hard on super soldier difficulty if you take your time and use cover during fight sequences. If you are having trouble however, I would suggest playing through on easy or normal and upgrade your suit and abilities. Once you beat the game, you have an option of "New Game +" which allows you to play through using the suit and upgrades you already have. I suggest upgrading stealth as much as possible, because in most situations, you can just run through the game unseen.
it'S called fastpass. when you send back a game and the post office scans it, gamefly is notified that your game is in the mail. they will update your gameq with the next game they will be shipping to you once they receive your game. that'S why it looks like there are more games out than you actually are paying for.
