During The International 11, Valve announced a new character who will soon be available in DOTA 2.
Her name is Muerta and her planned release date appears to be early 2023. Muerta shares many traits in her appearance with the Day of Dead in Mexico, such as flowers and skulls. She seems to be a vengeful gunslinger who can travel between life and death, but for the time being we dont have many details for her kit yet.
