Pros:
- Solid campaign that is far more emotional then previous Halo games.
- Great sound design and a decent soundtrack.
- New guns that add in more variety in combat.
- It's a visual treat.
- Great sound design that makes guns sound viscous.
- Solid multiplayer with great maps.
- Spartan Ops seems like a cool idea that can be cool.
Cons:
- A confusing story at times that requires you to research it instead of the game making you understand what is going on.
- It isn't a radically different take on Halo.
- You fight way too many Covenant,
- It is disappointing story wise as Halo 3's ending left it in a way that could make a different Halo story.
- The soundtrack isn't as memorable as previous Halo soundtracks.
