I only got this game as a way early birthday present from my Aunt, I must say that if she hadn't gotten it for me I probably wouldn't have/would have waited till I could get it at 19.99 or so. I must say that the single player mode is not as lackluster as the first (the dual weapons really for some reason make me like it sslightly more). the story still has tons of plot holes and isn't good at all. Since I got it last Wednesday, I have beaten it already on normal mode. Normal mode was slightly more difficult than the first's so hopefully the same will hold true for Legendary which IMO the A.I. really shines. None of the new weapons are really intriguing, some are fun but none are truly useful and you will find yourself mainly relying on the onlder weapons. The controls for the vehicles (i.e. warthog, banshee, the new wraith tank, etc.) all seem to be tighter. It feels taht you won't start spinning in circles as often as in the first. The LE edition (i know I just said it twice) is definently worth it. I like the box a lot but wish that they didn't stack the discs as they did as it makes it a pain to get the game out. The dvd is what really makes honkering down 5 buckaroos worth it for the LCE go the game. I've really enjoyed it/ I like the Making of documentaries because I wish to become aprogrammer/involved in the gaming industry. I've started to play the co-op mode on normal and it just feels like more of the same of the first's with the added improvements. Some cutscenes are really nice and interesting and will keep you captivated but others will make you just want to skip them and wonder why did they even leave that in the game. Music is phenomenal, really get your blood and adreniline pumping. Othe rthan the co-op mode the multiplayer is still the same. Unless you have Live or can have LAN parties every other day or weekend, you will forget this mode as they left out bots (again) and with only two people it really isn't that great and can almost make it boring. I must also add that it is much less linear it seem than the first one.
I gave the first Halo a score of about 7.5 or it could have maybe even slid by with an 8. This one I raise it to about an 8.5/9 with some of the improvements.
