Yeah said they are looking into it earlier, so they'll probably improve progression.
I played a bit last night. Can't say how it stacks up to Halo 4 or 5 MP, as I never played those. But i enjoyed what I played. Felt like Halo.
I will say that it's nice to see a Halo game getting hype again. Feels like this is probably the most hyped up people have been for a Halo game since Halo 3. I have high hopes for the campaign, think it looks like a lot of fun.
