This is the most balanced Halo to date. No more spawn kills and Invasion mode is so innovative and new. The new weapons are sick and there are still more we know nothing about. The vehicles have some tweaks but for the best. The next new thing is the armor abilities, like Sprint, Dodge Roll, Invisibility, Armor Lock, and the Jet Pack. These new features give Halo more balance and strategy. New weapons like the Sticky Launcher and Needle Rifle fit so well with this game. Older weapons also have had some changes. Like the shotgun, DMR, Magnum, and the Beam Rifle. To sum it up, the Beta is too much fun. If you haven't tried it yet, I suggest you do so before the beta is up. Oh and the upgrade system is based on points, no longer highest skill. Im maxed out in level as a Warrant Officer Grade 3, but there is so much more to look forward to. Uhhh the Fall... so far right now.
