News reported by Polygon paint the next installment in the metronome-like cadence of annual Call of Duty game releases as a much less interesting package than gamers are used to. Citing industry sources, Polygon is reporting that Call of Duty Black Ops 4 is going to shed its single player campaign entirely, citing a lack of development time to deliver it on launch. This is strange for a number of reasons. First, Treyarch, who's helming the games' development this time around, enjoyed a three-years development period to make the game happen; second, there's no need to do anything else than some incremental changes to the game's engine, as has been the case for COD games for years, so that couldn't have taken up much development time; third, using development resources to "just about" finish the games' campaign and then ultimately deciding to scrape it altogether just seems like a very bad business move.
