I picked up the game a few hours ago and got the free $20
gift card and ODST "Rookie" action figure. I want to comment on the action figure: I hate the joints on these McFarlane Halo toys!!! Most of the joints on my Rookie toy are stuck or too tight. I snapped the left leg straight off without much applied pressure. I appreciate the ingenuity and implementation that allows a wide range of articulation, but what use is that if they all suck? The right arm popped off at the bicep, but with a bit of glue and tack, I got it and the leg back on, but they don't work as good anymore. Good thing this toy was free. If I paid $12 for this thing I'd be heated.
Anyway, about the game: Played 3 hours or so of campaign. Loving it, especially the sound department (music and voice acting). Haven't tried the multiplayer stuff yet, but will soon. (XBL tag: Mega Rockman Z).
