Halo, Halo, Halo, what's all this then? 100GB of Halo content has leaked onto the internet, including a third-person demo.

After Insomniac Games, Rockstar, and the Pokemon Company were all hit by major leaks in recent years, Halo Studios has now fallen victim to a similar situation where almost 25 years of vaulted content from the shooter series has spilled onto the internet.

The big leak contains unreleased and pre-release content from Bungie-era Halo games from Halo CE up to Halo 3 and Reach.

The team claims that Microsoft neither paid them for their efforts nor provided resources and it appears that someone else decided enough was enough so a massive amount of content is now out in the wild for the PC community to do with as it wishes.
