Foxhole Annual Festival
The Foxhole Annual Festival is, as its name says, a yearly event. It was originally organised by the player base, but since 2020 it is organised by the developers and the Moderation team on a separate shard. During the runtime of the festival shard, players can participate in various special mini-games. Often, there are special recolored vehicles and sometimes even items that aren't released to the public yet. The festival kicks off with a parade every year.

History
The first festival was held on the 23rd of April 2017 during Weekly War #32, the last one before the implementation of Update 0.10. It was called "First Unofficial Foxhole Festival", and was fully organised by the players unbeknownst to the development team as a surprise. A large number of vehicles were made for a grand parade with many clans participating.

On 21st of April 2018, the Second Unofficial Foxhole Festival was held. A compilation of the second festival can be hound here.

Past Mini-games:

 * Capture The Flag
 * Urban Team Death Match
 * Hunger Games
 * Matt's 2v2 Tournament
 * Howitzer Death Run

The Battle of Red River
"It's a technology demo and special event that puts up to 1000 players on a densely packed battlefield. Set in the Foxhole universe, the Red River Demo will let you play in a unique part of the world's history that's never been previously expored. This demo is a proof of concept for new technology that about 10% of our team has been working on for over a year now."

- Nooba, via the Red River Demo Discord

The Battle of Red River was a demo event of the developers to test their new engine TP2 (Technology Platform 2). It functioned as a stand alone game download. The games took approximately 15 minutes each, and were run for a total 3 times on the 30th of November 2019. It featured unique character designs as well as models for a cannon for both factions.

Anvil
"For the last 2 years, a small part of the Foxhole team has been quietly working on an experimental server technology platform. The goal of the project is to push the limits of dense massively multiplayer experiences. To test this goal, we've created a medieval themed town building simulator called Anvil."

Anvil is a demo event of the developers to test their new engine R² (Successor of Technology Platform 2).
