First off, this game is amazing. The campaign could have been longer but that's true in every FPS. It looks absolutely beautiful, and as far as I'm concerned the balance between Armor Mode and Stealth Mode is so much better than in Crysis 1 & 2. I adore the Multiplayer as well, I have a few issues with it but I'll bring that up in a second. All in all though I feel like this is one of the few games I'll keep on the shelf.
A few glitches... There are the ones as of last patch I'm sure everyone's aware of. My dogtags reset every time I log off. When using expanded arsenal with a bow as the secondary, the bows cross hairs replace what ever weapon I'm using. Issues with the EMP kill streak not activating and becoming stuck on screen. Lastly on occasion when emptying my primary and needing to fast swap for that last kill, sometimes swapping guns just resets the reload animation leaving me high and dry in front of someone.
As for my issues with the Multiplayer, I feel like its very balanced in most ways, with the exception of a few things... My lead issue before any weapon is the Auto Armor ability, I feel like this is a great way to bring new people into the game who aren't used to the suit system of Crysis. I also feel that a good way to end people abusing it would be capping it somewhere between level 10 and 15, meaning once you reach that level it becomes locked, seeing as using it any more has no purpose. It has no upgrades and if you haven't learned to use your manual armor by then, you probably never will. (No offense meant)
My issue with two of the guns is kind of different though. I feel like the Typhoon and the Alpha Jackal are unbalance. I know that the Jackal is, I don't have any second thoughts about it needing at least one aspect (Rate of fire, Accuracy, Damage) toned down, not to say all three just one would be fine. On the other hand, the Typhoon I'm torn on. When I use it I feel like I have no idea how people are managing to slaughter me with it, but once I come across someone using it against me its as if they don't even need to aim. (Kill cams where as far as I know they shot my foot and K.O.ed me.) All in all I feel like it might not need to be tweaked as much as it shouldn't be a starter gun, maybe something you unlock via kill streak on certain maps. Kind of like the EMP/Ceph Ship only with the Swammer maybe?
Lastly a shout out to the Maximum Suit kill streak. I love this not because its overpowered, but because once I have it my main gun is almost always empty and I'm forced to use my pistol and melee. I find it fun to get a few stupid beat downs and pistol head shots before running into a group of enemies and getting mowed down when it wears off. I'm sure they only way it could be anymore fun is if when activated the back music changed to Sharp Dressed Man until it ended.
Thanks for reading, feedback welcome.
