Junkenstein's Laboratory

Junkenstein's Laboratory was a limited-time Halloween Terror game mode first introduced in Season 13: Spellbinder. In this PvP game mode, players could pick “mutations”, which varied from Common to Legendary. These mutations could affect the hero, or the entire team. The game mode ran from October 15 to November 4, 2024. On November 3, it was announced that the gamemode would last until November 11.

Gameplay

This game mode was a Team Deathmatch, played on various Control maps. Instead of a usual maximum 3-round game, this game mode can have a maximum of 5 rounds. To claim victory, a team must win 3 rounds overall. Due to this, certain Control maps will be reused and could be played twice in a match.

This game mode ran on a typical team format: 1 Tank, 2 Damage, 2 Support. When queueing, players could choose which role(s) they queued for, but the hero selection of the game mode was restricted to 12 Heroes. Additionally, players couldn't change heroes throughout the duration of a match: the button to change heroes in spawn instead redirected players to their page of hero mutations.

There were other slight changes in this game mode compared to a normal Team Deathmatch. 'The Narrator', who usually narrates the story of other halloween Terror game modes such as Junkenstein's Revenge, replaced Athena during this game mode. During which, instead of Play of the Game he says, “Slay of the Game”.

Throughout the game, players picked mutations to improve their kit in various ways, unique for each hero. Players started with 2 mutations, each round gaining 1 for a maximum of 6 mutations. This meant each game would be different in slight ways, with hundreds of combinations for hero mutations.

Heroes

During this game mode, the hero selection pool was limited to only 12 heroes: 3 Tanks, 5 Damage and 4 Support. These heroes were pre-equipped with Halloween-themed skins, as listed below.

Tanks D.Va (Shin-Ryeong) Reinhardt (Coldhardt) Orisa (Demon)

Damage Ashe (Warlock) Genji (Stone Crow) Pharah (Enchanted Armor) Reaper (Pumpkin) Soldier: 76 (Slasher: 76)

Support Kiriko (Divinator) Mercy (Conjurer) Moira (Banshee) Zenyatta (Zealot)

Mutations

Mutation Page for Genji

The mutations are divided into four 'rarities' of 4 colors: Common, Uncommon, Rare and Legendary. These rarities can also be indicated by the number of pumpkins on the mutation card, from 1 to 4 (common to legendary).

Players started by picking 2 mutations, and each round could gain 1 additional mutation. They could also discard a previous mutation for a new one, if they wanted. After a maximum of 5 games, a player could have at most 6 mutations. In the mutations page, players could see their mutations, their teammates mutations and even the enemy's mutations. These were also visible after being eliminated, whilst spectating your teammates in a collapsible tab on the right of the screen.

Trivia

• Junkenstein's Laboratory might've been a direct teaser for Stadium.
  • The mutation system was split into powers and items: powers are permanent and change the hero's playstyle, while items can be sold and provide statistical buffs with optional side effects.
  • Like Junkenstein's Laboratory, Stadium features round-based gameplay where instead of switching heroes the players counter by building them up.
