Halo Infinite's multiplayer on Steam has seen a significant drop in player base, losing around 98% since its launch. Concerns arise about the game's future, but it remains free-to-play with updates.
They flopped hard. The game lacked content, ran poorly, and had one of the most aggressive monetization I've ever seen. They sold armor color palettes for $15, and doubled down hard after community backlash. The game launched without singleplayer, and when it did the singleplayer sucked.
It sucks that this was supposed to be Xbox's killer first party title, but the devs were just totally incompetent.
