I love this game, especially the airborne jumps. My only gripe is that the NPC's tend to take the best firing postions.
I love the background sounds. I got a new big screen with decent speakers, so now I better appreciate the distant bass crump of artillery fire that backs up the staccato small-arms fire.
I have just a couple complaints about the game. On the "hard" setting, the bad guys turn into Magic Nazis. Their one-shot kills and/or their focused fire while Keegan maintains good cover in the dark are goofy. They also seem rather difficult to kill. To get around this I took my time and used the headshot. My other beef is that your NPC buddies tend to take the best firing positions. If you get there first, you get pushed out or you'll be unable to peek around your cover to get a shot until you back away. Your squad members also often step in front of you while firing, a major gaff real soldiers avoid.
Even though this is an installment in a long-lived game series, it still provides fun gameplay.
