OMG I have had the newest halo game ever since it came out but I just thought about talking about it today. so it is still a first person shooter unlike halo wars, but anyway it is manily about finding your lost squad of odst in the lost city of new mombasa I will not ruin the ending but it is cool it is only an expansion pack but worth the money.It goes between night and day between odst.Oh and there is a new thing called firefight it is basically like the hored mode on gears of war but it has more of that feel to it because on hored once I got so far I could think and know what was coming but on odst they are at random so it is harder.
