I just finished playing up to the 7th mission and holy shit this game rocks. I'm a big RTS guy and I have all my RTSs on my PC but this works so well on the console. I should have got the LE for the codes, could def use that money since I can't play Halo 3 online. So, I just finished mission six where, without giving anything away, you have to defend against 5 different attacking positions. Wow, let me tell you, I'm on normal and I had a challenging time on that one but it was a lot of fun to play. I came back from having my main base in the red! Spartans hijacking airial units is hilarious, whoop, bang bang now its mine, lol. I hadn't played the demo in a while so I totally forgot a lot of crucuial things like upgrading your fire base to get additional buidling slots. I see a lot of replay value with this game as well since I found one skull and black box but figure there are plenty out there to grab. If you like RTS games, like Halo and have a console you should def get this game.
