WARNING: This is just my opinion! Don't nerd rage over it.
Graphics: 9/10
Textures: 10/10
Models: 10/10
Effects: 9/10
Optimization: 7/10
Conclusion: The game just looks beautiful in its open environments and brings back good memories of Halo: Combat Evolved. Sadly they did overdue some stuff like the overuse of motion blur. Just people walking are emitted with motion blur and it can be very annoying. Optimization was also poor. I'm guessing this was built for the newer 360s that have better specs but not everyone has those versions. I get some noticeable frame rate drops especially on the first mission in campaign.
Gameplay: 9/10
Single-Player: 8/10
Multi-Player: 10/10
Conclusion: The game's campaign is relatively short based off my friends and it doesn't offer a big difference from the other Halo campaigns. The only new thing is basicly the space fights which I have yet to still reach. The multi-player is just great though! Their matchmaking has definitely been kicked up a notch but you can no longer view films in theater with friends anymore.
Stability: 8/10
Glitches: 7/10
Graphic Tearing: 9/10
Conclusion: There are still some glitches left over from the beta that apparently they neglected to fix. There were also some noticeable cases of texture tearing but I believe that was caused by their new "Impostering" system.
CONCLUSION: The game is really enjoyable but I feel that it seemed rush. There's not a lot of maps and most of the maps are forged maps in Forge World. There have been major improvements though and I suggest grabbing a copy whenever you can. Where the game lacks in some places, it also makes up for it. This game gets an overall rating of: 9.5/10
