Your Dota 2 announcer of choice might just change today now that the narrator from The Stanley Parable is available for purchase. Normally $9.99, this announcer pack is currently a dollar off.
I'm not a Dota 2 player by any means, but I accidentally listened to a good 15 minutes of narration. While I think this is a fun voice-over even if you haven't played The Stanley Parable, doing so is advisable. Seemingly in light of the DLC release, the game is half price until May 19
