Just played some Homefront multiplayer for about an hour and a half. It's quite enjoyable, but it has its faults. For one, mouse sensitivity while aiming down your sights is different than hip firing, and if you play with a high sensitivity its impossible to match you ADS sensitivity since it doesn't go up nearly as high. Also, if you're looking for state of the art visuals, you may want to move along. The game is passable, and at times looks pretty good, but I forsee PC graphics whores bitching.
That said, I am enjoying the gameplay, maps are great, and the Battle Commander thing is pretty awesome. I have yet to touch the single player though, so I cant comment on that.
