To the people questioning this review.... don't... they are legit. I have beaten the campaign on legendary (i'm a pirate I know... but my little brother was stupid and logged into my account a few days ago and it permanently banned... karma lol) and what they said was true. Probably took me like 10 hours to do it on legendary as I'm a pretty good halo player. This is definetely the best first person shooter I have ever played. They keep mixing up the gameplay to make it interesting.
For people interested in the credit system, i've done some experimenting and it's all based on time. Did 5 minutes on firefight normally killing dudes... 297 cr. 5 min firefight being invincible and killing like 2 guys... 297 cr. Playing 5 min custom games was 297, 5 min of campaign was 297. The max amount of credits your allowed to get in one session is 4455. Which is 75 minutes. So I bought a play and charge so I could accumulate points but then I got banned.
If anyone has questions about the game I will answer them.
