Halo Infinite began its Season 2, titled Lone Wolves, earlier this week, but the introduction of the new battle pass seems to have an unexpected consequence for those who didn’t finish Season 1. Those who still want to progress through the Season 1 battle pass are finding one of their progression slots locked and buying the Season 2 battle pass is the only way to unlock it.

Spotted by a Reddit user and confirmed by GameSpot, the challenges available in the Season 1 battle pass are now different than they were before. Previously, four challenges from the weekly queue would be available at any one time, meaning you could progress in these simultaneously and speed up your experience earnings. However, only three are available now, with the fourth telling players to upgrade the Season 2 battle pass in order to unlock this “extra” challenge slot.
