If you’re a Call of Duty fan who’s still playing on PS3 or Xbox 360, it might officially be time to upgrade to a next-generation game console.

Publisher Activision announced today on its blog that the Xbox 360 and Playstation 3 versions of Call of Duty: Black Ops III will only include the series’ multiplayer modes—so the portion of the game in which you shoot other players, and the “Zombies” mode where players band together to fight off waves of the undead. The story-driven “Campaign” mode will only appear in the PC, Playstation 4 and Xbox One versions of the game.

Activision says the reason the campaign is being held back is because it supports as many as four players working through the game cooperatively. The older consoles just can’t handle it, apparently, so you’ll need to upgrade to Xbox One or PS4 in order to play through the game’s story.

Traditionally, Call of Duty’s most popular modes are the multiplayer ones, but that doesn’t mean the rest should be discounted. The “Black Ops” games is known for having some of the better stories of the series, and Call of Duty: Black Ops II’s narrative was one of the best modern shooters have seen in a long time. That game included multiple endings and branching paths based on the decisions you made, or whether you succeeded or failed on missions.

So for the full Call of Duty experience this year, fans are going to need to throw down a few hundred bucks for new consoles if they don’t already have them. Best keep those eyes peeled for Black Friday deals.
