Halo Infinite Spoilers Warning

A couple of tweets from Joseph Staten on Twitter have a warning from 343 Industries' campaign project lead on Halo Infinite. He cautions that the tech preview build that's now in the hands of some of the public contains data from the main campaign in the upcoming first-person shooter. So be careful about the possibility that there may be previews and other information appearing that could end up spoiling the game for you:
Hey folks, heads up: we unintentionally included a small number of #HaloInfinite campaign files in the tech preview build. Unfortunately, these files contain spoilers.

Leaks like this are painful for the dev team and can ruin the campaign experience for everyone. So please, keep you eyes peeled for spoilers and don't spread them if you see them.
