i& #39;ll finish this article if you all tell me what games you consider (or were marketed as) halo killers. obviously there& #39;s killzone and haze.

rt for as wide a net for answers as possible

I want marketing as a Halo killer, not a game you would consider an attempt at one. "Why the Halo killer failed" is a useless article if you go "well I personally feel that x is a halo killer"

the premise is "other people tried to make halos--why didn& #39;t those games catch on?"
