Game is great. Just like the first one, in NEVER gets old. The new realism mode is sick! This definitely kicks the difficulty up a notch. The graphics are improved, I shot a zombie in the stomach and saw his large intestine droop out of his body, although he continued to attack me further til I put another hole in him! The only issue was that I was still having fun playing the original left 4 dead. There do seem to be alot of people who suck at this game online. Also if you play online, get a damn microphone because it is essential for this one. I could only play one game the rest of my life it would be this one.
