On the 31st of October 2014, Vlambeer introduced a new type of enemy into Nuclear Throne, as well as covering all areas of the game with mist and having a wolf howl play at the start of every level. This new enemy behaves and has the same stats as the regular Bandit, but has a small aesthetic difference: it wears a mask that looks like a Pumpkin with a carved face.
Halloween Bandit, the mist and the wolf howl will appear in the game each year on 31st of October. During that day, one or more Halloween Bandits can spawn on every area in the game. The Halloween content is removed on 1st November.
