Call of Duty: Black Ops 4 was always more of a collection of games than a single release, and Activision has finally decided to offer a less-expensive option for players who don’t need to have it all. The “Battle Edition” of Black Ops 4 is now available through Battle.net, and it comes with the game’s traditional competitive multiplayer mode and Blackout, Call of Duty’s battle royale mode.

The bundle will be available for $29.99 until Jan. 6, 2019, when the price goes up to $39.99. For now, however, you’re basically paying half-price for a version of Black Ops 4 that includes everything except the Zombies mode.
