Enjoyable but nothing great
A few points that didn't get mentioned since I don't care for consoles this ofcourse reffer to the real platform to enjoy fps games on.
Graphics: While the graphics are ok, they don't impress like farcry or crysis did. The environments while ok are not anything special, and some of the nature parts seems to be a bit low on the polygon count. There is also a strang omittment in that the game has no builtin advanced settings but only resolution and a high mid low kindof setting though a bit of googling turned up a application that allows you to change the settings as you please .
Controls: The controls work decently well and are not useless as many console ports are.
AI: Pretty useless.
Now onto the important stuff
Gear: There are two kinds of hardware in the game, weapons and the suit, let's start with the suit.
As in Crysis stealth is the name of the game most of the time, once in a while armor is also helpful, but stealth is what will see you through most of the game. The suit can be upgraded with enhanced abilities in four categories with three different options availible in each, unfortunately they have very different usefulness for the singleplayer campaign (the multiplayer upgrades are a bit different) it's also somewhat annoying that the cost for the different upgrades vary so much that you in reality have very limited choice on what upgrades to use until very late in the game. Overall though the suit feels a bit more pollished then it did in it's first incarnation.
Weapons: The weapons in the game are a decent collection, but somehow I miss some decent firepower upgrades it seems like I prefered to use the same weapons all the way through the game with a upgrade from assaultrifle to machinegun as soon as I get my hands on one. There are two hightech experimental weapons in the game that you can pick up at a couple of places, while good they suffer from not having amunition availible to replenish the initial loadout which limits the usefulness.
Gameplay: While you usualy can do things a couple of different ways it feels like you are mostly firmly atatched to the railroad tracks and are not allowed to deviate. While taking place in new york you realy have no way to move around like farcry or even crysis allowed you to do. The aliens come in three varities standard cannonfodder annoying cannonfodder and annoying amunition sinks. One strange thing is that while storywise the same aliens as in crysis they have apparently changed equipment since they bear no resemblance to the flying squids etc in Crysis.
From a leveldessign standpoint it's a clear move back from it's predecessors andshow little if any innovation.
Is it fun: The game is decently entertaining and the story is not bad, though I can't shake the feeling that I spend to much time falling from high places or drowning. or a combination of the two.
