I just played my first 2 games. The first was standard deathmatch, and the second involved capture points. In the second, I ran into my friend Chase on the other team and we concluded the game by simultaneously killing each other. That was pretty sweet.
I'm actually halfway decent from what I've played so far, getting 1st and 2nd place on my team in kills. My experience with 3rd person shooters is limited to Gears. I had never played a RF game, but I'm really, really liking the game so far, though. Seems like a buy.
