why do people think halo 4 is gonna cod?

I keep hearing people talking about being worried that Halo 4 is going to be like call of duty. I dont understand why they think that. can someone please explain to me why?

Because some people have their -Yoink!- in a bunch cause of sprint and we finally get to choose our starting utility weapons instead of having to worry about DMR/BR vs AR starts.

Because they fear that adding in elements that are similar, if not the same as, elements that characterize Call of Duty (Custom loadouts, join-in progress, ect.) will simply make it CoD in space.

Players are afraid of the similarities between the two. But rather than looking at the similarities, they should look at the differences. 343 will improve on the gameplay and execute it better than CoD ever could. Halo 4 is going to awesome and just because 343 took over Halo, it doesn’t mean they don’t care about it. I’m interested to see what they bring to the franchise.

“is gonna cod”

Are you using that as a verb?
