I got it the day it came out. Pre-ordered it. I got Sgt. Johnson for firefight. It's pretty gay how he was made. It's just Sgt. Johnsons head on rookies body. Eh, it's okay. You still get to be the coolest character (Besides master chief) in Halo. Not too great on graphics when it comes to the humans. The rest looks great. That's a really dark game. Your helmet has a little function where it lights up, shows enemies as red and allies as green. The game reminds me of Metroid. You have to find different areas, fight many different foes, and find many different weapons, including weapons from halo 1, 2, and 3. For example, they pretty much brought back the first pistol, but it's black and looks awesome. The assault rifle from halo 3 is Bucks main weapon, and for Rookie iit's a new silence assault rifle. I have't gone passed them yet, but I know one thing for sure... Normal +, if you're not careful, a few grunts and jackals can take you down easily. You're not chief anymore, so that means no more overshields and strong armor, just stamina and health. No more lowered-gravity, you jump like a human now, but of course, since you're pretty strong, you can jump like 5 feet.
