They have hired former professional Halo players to be involved in designing and contributing to the game mechanics. I'm very impressed with what I've played, and it feels like nothing is being left to chance. They've introduced new and old mechanics that makes the sense of mastery greater, while the game remains relevant and inline with modern shooters. Personally, the ranking system is something I am most excited about, and even though the beta doesn't include any ranking, I'm looking forward to playing it again this December."
