League of Legends is introducing the doom bots of doom starting July 17
Riot Games will begin a new, limited time League of Legends game mode — Doom Bots of Doom — starting July 17-27
Doom Bots of Doom tinkers with the abilities of in-game AI bots by increasing those abilities in a few ways. For example, in typical games, the ultimate ability of game character Lux will be shot as a single laser; in Doom Bots it will burst out in all directions.
Those who challenge them at least once will also recieve a Doomtastic summoner icon.
