Valve has registered the trademark Dota Underlords, the object of which is still mysterious. The registration has been applied for the may 6, 2019, and accepted three days later.
Dota Underlords could hide a new game, a new mode of Dota, an expansion dedicated to Vogros the Underlord, or who knows what else. Many believe that it will be officially announced during the International tournament of Dota 2 which will be held from 20 to 25 August 2019. The rest of Valve’s chosen the International two years ago to announce the Artifacts, the game of cards in the series currently under review, the total (or disposed of, according to the most pessimistic).
Another hypothesis, less likely, is that it is the first of three games developed by Valve to display VR. In short, the current state is really impossible to give concrete form to the various possibilities in the field, then we just have to wait. In the meantime, we remind you that Dota 2 is a Moba free-to-play downloadable from Steam.
