Story
The story is simple if you want it to be.
You are a soldier identified as Noble Six. You and your team are fighting to keep aliens off of a planet called Reach. You fail.

Yep, It's a Halo Game.
This is Bungie's last Halo game, so don't be surprised when you play this game and think "This feels like Halo."
Yes, it plays just like Halo with a few differences. If you hate Halo, you probably won't like Reach. That being said, if you love Halo games or once enjoyed Halo but eventually parted ways for other shooters (as was my case), give Reach a shot. At first glance it plays just like a Halo game for both single player and multiplayer. Energy Shields. Assault Rifle. Needler. Plasma Grenades. Tank Level. Announcer Guy. It's important, though, that I point out some differences. Your health is back, much like it was in Halo: CE and ODST, and technically you aren't the Master Chief. Since you aren't the MC, Bungie added customization options for your Noble Six.
Customization
Customization works via credits, which are earned across most game types. As long as you're playing single player or anything in matchmaking, you earn credits. Credits you earn can be spent on new armor and effects for your Noble Six. Armor pieces are purely cosmetic, and do nothing to actually buff your character's stats. Oddly enough, the thrill of upping your look becomes intoxicating, motivating you to play more and aim to complete every day's daily challenges, which give you credit bonuses.
At first glance you might not think there are really all that many options for customization, but once your character begins to level through the online ranking system, more options become available for purchase. I don't personally know how far the ranking system goes, but it is a little intimidating knowing that I might buy a helmet I really like only to know that a better more expensive one may pop up as soon as I reach my next rank.
When I got the game the first thing I did was play through the campaign, and I had trouble figuring out which SPARTAN was my SPARTAN, but once I had spent some time in multiplayer and had taken time to customize myself, it was much more apparent which one was me, which sometimes made a difference to how I felt during the cut scenes.
Weapons
Now I'm not going to go through all of the weapons here, since most of the weapons have been around a while, but I will draw attention to some of the more notable new weapons in the game.
DMR

Needle Rifle

Plasma Launcher

Multiplayer
Multiplayer has been one of Halo's claims to fame ever since Halo: CD, before they were able to introduce online play with Xbox Live, and Halo: Reach does not disappoint. The multiplayer and matchmaking systems in place are the most solid they have ever been, and the online gameplay is great. Granted I'm talking about hoe the game functions and leaving the "Halo Douche" stereotype out of this. There will of course be those who get online and ruin the whole experience for everyone for whatever reason, but I'm leaving them out of this review. There are plenty of game types available for online matchmaking, ranging from the traditional slayer to Halo ODST's Firefight, ensuring that there's plenty for you to play.
In Conclusion
Halo: Reach is another Halo. It feels as much like Halo as any other Halo ever has, but it is certainly refined and renewed my interet in playing Halo games. I wouldn't call it the best game I've ever played, but it's well up there in my favorites. If you like Halo, give Reach a shot. If you hate Halo, this probably won't change your mind. I'm also realizing I neglected to mention both armor abilities and assassinations, and I don't currently have the time to write about either of those, so I apologize for forgetting about two of the more prominent changes in this game.
