My favorite aspect of this game is the way the levels are designed. Instead of having to run through tunnels like Doom 3 or be forced to stay within a tight little area like a Medal of Honor game, Crysis gives you plenty of wide open space where you can decide your best approach. This means you should save the game often, as your strategy often backfires until you find the best way into a heavily armed area. I much prefer coming up with my own strategic attack plans than being forced down some linear path and participating in a pre-programmed shooting gallery.
The AI in this game is pretty smart, but I like to throw it off by sniping enemy soldiers with a silenced rifle. When enemy soldiers don’t know where a shot came from, they’ll duck and look around. It’s kind of funny to watch. In the heat of battle, soldiers will come after you some, but they will also seek cover. Not only do you have to keep your eyes peeled, but you need to turn your speakers up to listen for audio clues. The enemy soldiers tend to shout back and forth to each other when they spot you, so if you hear somebody yelling you better seek cover or start shooting.
Your soldier will have a wide variety of weapons available, though ammo for the really good ones will be limited. Although I have come close to running out of ammo during a couple of heavy encounters, I was always able to find a stash somewhere, or I could just steal it from the enemy soldiers I killed. In most of the big gunfights, you’ll find stuff laying around that will blow up, and this can be used to take out many at once. In one part, you can actually blow up a gas station, but make sure you aren’t standing too close or you’ll get blown up, too.
