You know, it's kind of gay when you spend 20 minutes to get large enough that soldiers can see you, and one bullet can kill you. Especially when the red line pops up about halfway through the area.
I don't see why you need more than one attack(two if you count the absorb blast thing, which more people need to figure out). It's a more of a puzzle/adventure game then a fighting game.
I'm not sure if you can do this in other operating systems (too lazy to find out), but, in Vista, you can just turn down the volume for Firefox, but still have another appplication's volume unaffected (Media player, Zune, etc.), so it doesn't really need a mute button.
