I went over my friemds place, went on co-operative, difficulty on heroic. We finished the game in less than a day of having it. I'd have to say it had its ups and downs. Firstly, I know they tried to make it different by having 2nd player be the arbiter but COME ON! You should be able to choose between master chief and arbiter, but you can't. And another downside is the sniper covenant! Me and my friend spent most of the second level shooting sniper covenant and I HATE them! It's good to have just about 5 in a whole level but I swear there was about 30! But of course a game this hyped has to have upsides and it does. New really kool vehicles like this one vehicle that I used in versus mode and I swear its invincible. My friend was shooting at me for like 5 minutes in that thing and I didnt take a hit. It was funny when he hopped onto the side of it because there are these things called 'the guardians' that when you go too far out in a versus level they shoot you. So when he was on the side I drove him out there and he died first but yeah i still died afterwards.
The flood are on your team for like less than half a level but when there is flood, you guessed it (or didn't you?) there is Guilty Spark. Guilty Spark is the MOST
annoying character in the whole series of Halo.
But don't worry, you get to kill him in the end anyways.
There are loads of new features such as taking turrets and you could walk around with them the whole level if ya wanted to although it is in 3rd person mode. When you get melee'd you can fly away and re-watch it over and over in the theater. The theater is the place where you can see your gameplay videos of campaign or versus mode whether in fast, slow or normal motion. Another new feature is the different types of armour you can unlock. Although most of the ways you can unlock them is through online play getting new armour is always kool. I really want the HAYABUSA ARMOUR!
Thats it for now
