Rick and Morty, heroes of theabout an insane scientist and his grandson, are making their way to Dota 2 in the form of an announcer pack.
There are several of these, featuring such memorable voices as , the narrator from The Stanley Parable, and Half-Life's very own Dr. Kleiner.
Basically they replace the default announcer for things like score updates, first blood calls, Mega-Kills and so on. Voice actor Justin Roiland is clearly having a great time, as you can see for yourself in the video below.
