I'm not satisfied with the game, and here's why.
As an Orbital Drop Shock Trooper I was expected some epic battles. Bursting into a combat zone with my allies taking on the Covenant with my fellow allies, but no.
Instead, we got one lousy drop. WTF!?! And it wasn't even awesome. Instead you wake up 6 hours later?!! and of course..the action was over. Now, instead of an awesome campaign battle, I had to walk around looking for items so "Rookie" can have supernatural flashbacks? Please....
The second CD....I feel scammed. Bungie sold us their same product, twice. Halo 3 Multiplayer and Mythic Maps (for those bought them). But oh, look! 3 more maps! Great. What a bunch of bull. I did not pay $60 to buy 3 maps. Indeed, that was a low blow.
Firefight...fun..but once you get the achievements..who cares? Boring, replace it with Halo 3.
The game is overpriced, and I feel Bungie should release some real ODST missions. I wouldn't mind dropping next to the chief during the Halo 2 missions, maybe the perspective of the other troops. We fight this battle while the Chief fights the other. There needs to be some allusions to the original game, there wasn't even a mention of the Chief.
Please Bungie, just release some new campaign missions, for me the story is most important.
