This is a great example of what a sequel should be.

Everything from the story, to the gameplay, and the level design is improved from Combat Evolved.

Allowing the player to dual wield weapons along with a whole new variety of them kept the gunplay much more fresh than the previous game.

The music is, once again, incredible and adds such a badass feel to even just driving around in a Warthog.

My only real complaints are that:

1. the bosses were a bit spongey. Maybe that's because I played on Heroic difficulty but it still felt like a little bit too much.

2. Having no compass or map or even proper context clues on where to go really dragged down the pacing. Having less level repeats is good, but at least I would know where to go the second time through for those.

Realistically those are super super small complaints, this game is really that good and it's only kept my hype going for the third one.
