Lame designs, besides it cant be the covenant since it was destroyed/disbanded at the end of Halo3 It has to be the "ancient evil" aliens...
After playing reach last year I came to the conclusion the Halo series was way past its prime. In my opinion Halo 2 was the best in the series and I know the story was up and down in places but the online ruled. Not excited for this one at all but you never know maybe I'll be proven wrong.
Interesting, hopefully more details will come out soon. This is the main game I am waiting for this year.
I was never a huge Halo fan, but to me it almost seems like it's heading in the same direction as Shrek. Way to many sequels. Sometimes, a series needs to end, and end well.
