Seasonal events - Deadlock Guru

Seasonal events are temporary holiday celebrations. The 2024 Halloween event ran October 31–November 7; the 2025 event ran October 24–November 12. Halloween added four randomized hero masks and pumpkin models for boxes, statues and Denizens. April Fools 2026 allowed multiple copies of the same hero in a match.

Winter 2025

The event ran December 15–January 20. Players received a Snowball item that leveled up through wins with different heroes, also unlocking Hideout Christmas-tree ornaments. Participants received a souvenir above the Hideout fireplace. The Shopkeeper gained holiday lines for all heroes, and Drifter gained seasonal songs for Eternal Night.

Winter 2024

The event ran December 17–January 17. It added a menu animation, remixed menu and shop music, decorations throughout streets, buildings and the Curiosity Shop, a Santa mask and special Shopkeeper lines, snowman Denizens, and holiday lines for Dynamo and the Newscaster. Participants received a Hideout fireplace snow globe. The winter shop’s nice/naughty list marked only Lash naughty.

Mainline heroes had unique skins unlocked by challenges. The community discovered the conditions; they were not listed in game or patch notes. Each challenge had to be completed in a single normal or Labs match, not custom or bot games. A Santa-hat menu icon tracked the count, and unlocked heroes had a hat and red background on the Heroes page. The profile Showcase also listed unlocked skins.
