According to a Reddit post by u/ske7ch343, also known as 343 Industries’ community director Brian Jarrard, Halo Infinite will get Slayer, Free-For-All (FFA), Tactical Slayer (SWAT), and Fiesta playlists (via Windows Central). Jarrard stated the four playlists would be added to the game in a December 14th update.
343 Industries had stated that Fiesta, SWAT, and FFA playlists will be available by the end of the year, but that a Social Slayer playlist would not be available until 2022. Jarrard concedes in his essay that the creators promised a “variety of additional permutations” for the Social Slayer playlist. Because this wouldn’t be finished in time for the holidays, 343 chose to start with a basic Slayer playlist and then “seek to enhance and extend with more varieties” in the future.
You can’t pick your game mode right now. You’re forced to switch between Capture The Flag (CTF), Slayer, Strongholds, and Oddball, which is inconvenient if you favor one game style over another. It’s especially inconvenient if you’re charged with completing a challenge that matches to a certain mode; however, 343 is responding to this concern as well, stating that the December 14th update would eliminate “particularly irritating” mode-specific obstacles.
In addition, the update will reduce some challenge criteria, making the weekly ultimate challenge “less rigorous,” and include tasks tailored to the future playlists. 343 is also working on implementing performance-based XP, which is presently unavailable in the game, by creating a challenge category that is “based on accumulated player score.”
Players who want to level up are now only rewarded with XP for completing challenges, not for each game they play. This has been a significant gripe among those who want to level up. 343 attempted to solve battle pass progression concerns last month by introducing a “Play 1 Game” challenge, lengthening the duration of XP boosts, and awarding players with additional XP for the first six matches they play in a day.
Jarrard also mentioned that developers are working on fixing the “intermittent hiccups” that appear to affect Big Team Battle (BTB), as well as looking into ranked matchmaking after hearing reports of “potential anomalies.” Despite the fact that Halo Infinite was released on December 8th, players are still waiting for the co-op story mode, which is set to arrive in 2022, and a way to replay individual levels in the campaign, which is set to arrive in 2023.
