Great game, while it lasts.
1. While the game is stunning to look at you can't really explore the whole map, you have a set course and you basically just follow that to your objective.
2. The campaign is very very short. For someone like myself who likes RPGs and games like Metal Gear Solid that take at least 20 hours to beat this game's campaign was pretty dissapointing. The story really isn't immersive at all, you go here, do this, get out. The ride is fun but why am I on the ride in the first place? The voice acting is ok but the cut scenes are a little weird because while you're watching it the characters are just doing the same things over and over again.
3. Graphics are out of this world (literally) everything in the game has great feel to it. The game has a great sense of weight (unlike halo) and the gun selection is fantastic.
4.Multiplayer is great, there's always someone to play. It gets a little crowded but that's ok IMO.
Overall I gave this game a 8.5 because the multiplayer is great and the gameplay is unlike anything I've played before. I was very dissapointed with how short and untapped the story was. Very good game, much better then Halo IMO.
