I got in on the Halo 3 Beta via purchasing Crackdown (the next day I got an invite via the Friends & Family program, but turned it down figuring someone else needed it more).

I’ve played about 2 hours worth, and here are my impressions:

1. It’s still Halo, which is good. You hop in in seconds and you’re basiclaly set.
2. New maps are decent.
3. Graphics aren’t that much better than Halo 2, but should get spit and polish (there’s, like, no bump mapping, blooming, etc)
4. The single player will be a lot of fun, as will online coop
5. At this point, I’m not convinced I want to plop 60-90$ down on it…
