Get ready for fresh ways to play in Halo Infinite, as 343 Industries has announced a number of new playlists, including the classic Slayer, are dropping tomorrow. Some of the Slayer variants promised won’t be available yet (expect those in the new year), but 343 is providing a basic Slayer playlist for those eager for some holiday slaughter. Here’s the official rundown on the new playlists…

Four new playlists: Slayer, Fiesta, FFA, and Tactical Slayer (SWAT) will all be added via a services update this week. the team's original plans for a Slayer playlist included a variety of new variants that weren't going to be ready in time to deploy before the holiday break. To address player feedback for Slayer in the near term, we'll be releasing a basic Slayer offering to start and will look to bolster and expand with more variants in a future update.
