In just a few days Activision and Treyarch will officially reveal Call of Duty: Black Ops 4 to the world, but that isn't stopping them from teasing the game. Yesterday, Call of Duty's official Twitter account released a gif that gives a hint, although not much, of what's to come in the next couple of days.The gif is incredibly hard to see, although it appears to feature a soldier and a rifle being locked and loaded before the infamous "IIII" logo appears on the screen. This really doesn't show much from the upcoming first-person shooter, but that should really come as a surprise when we are so close to the actual reveal. You can, as always, check out the gif and tweet at the end of the article.In other Black Ops 4 news, a couple weeks ago Treyarch started teasing the game's multiplayer on their Twitter account by showing off pictures of the perks and "pick 10" system that will be featured in-game.Call of Duty: Black Ops 4 is set to be released on October 12, 2018, and will be available on PlayStation 4, Xbox One, and Windows PC.
