The event is set to end on November 7th, 2021. As compensation, owners of the item up to that point received a free random item from the Crimson Cache case's drop pool. Previously available as a Mercenary Grade item in the Crimson Cache case, the item was removed from the case's drop pool, and moved over to the bonus item drop pool instead. On October 11th, 2021, the Corpse Carrier was retroactively given a holiday restriction. Soul Gargoyles were given out during this time to players who launched the game and did not yet have one. On October 5th, 2021, Halloween Contracts were activated, the Special Event menu was updated with the featured new Halloween maps, and Soul Gargoyles began collecting souls.
The update will be applied automatically when you restart Team Fortress 2. On October 1st, 2021, holiday-restricted cosmetics were activated, and the Special Event menu was added to the Casual mode selection with Halloween maps from previous events. An update to Team Fortress 2 has been released.
