BotB has had a lot of different XHB series in the past years. This article tries to list at least the most successful and commonly known ones.

'[#[Summer Allgear Series]
The Summer Allgear Series is a notable '[[XHB] series ran by '[l[https://battleofthebits.com/barracks/Profile/hanna/[hanna] during the season of summer. It is considered the XHB counterpart to '[[Summer Chip], in that it mainly uses the '[[allgear (format)[allgear] format for submissions, as opposed to the regular chipist formats used in Summer Chip.
