"The first thing I noticed was how different the game felt from any other FPS I have played in the past. The physics are impressive. My gun actually felt like it had weight to it. Turning and aiming have a tiny lag to them like they would in real life. Slammed into the heat of battle against the Helghast on their home world, suddenly I was very aware of where I was aiming. In a game like Call of Duty, one could get away with shooting a little bit to the right or left and still hit their mark. It's hard to articulate how the difference feels until you have the controller in your hands. I liked this change of pace; it feels like I was provided with an actual challenge instead of having the game aim for me. The AI is sufficiently decent, at one point while trying to destroy a bridge I was surprised attack from all sides. It made for an interesting gaming experience not plagued by stupid opponents."
