Bungie and Microsoft seriously accomplished perfection here!
The graphics, the audio, the storyline is all just absolutely amazing!
Now, i am not a rabid Halo fan like some people are and i don't care all that much for multi-player scenarios, but this game has amazed me! It NEVER disappoints all the way up to the ending scene(s) and (not to give too much away) that last Hail Mary jump to safety scared the heck out of me and I was left speechless for a few seconds, in disbelief that I made it in time.
The ending leaves you completely satisfied. All of the memories come back to haunt the player and all of them culminate. I have said it before and ill say it again, this is probably the most PERFECT ending i have EVER seen in a video game or movie. i Swear, you will not regret playing this game.
New weapons, the addition of deploy-able equipment, and the sneaky tactics to carrying 3 major weapons at a time and i don't mean dual wielding. Last but not least I am glad to see more of a requirement for early preparation to get through some of those firefights. Otherwise if you go in guns blazing against even a handful of grunts, chances are you wont last very long... ;)
