They have an Article/Video/Wildcard bounty campaign hosted on their site. I'm not aware of a Bitcointalk/SocialMedia bounty campaign yet and I doubt that'll come.
I suppose they wish to do their marketing through Articles/videos & similar ways.
yes I have seen this bounty on the website. I also saw the participation in the festival of games, but it is a very narrow promotion. here we need something very wide which will sow a lot of grain. gentlemen, devs will plead for promotions, unless you do the game just for own satisfaction and several people.
why is always like a good product and a team of developers marketing is defeat, and the whole project is a failure?

you do like this devs team, finish it like this thread:
https://bitcointalk.org/index.php?topic=1630816.3120Marketing is already going on. They have got a nice response from game conferences and blockchain summits. I think onboarding of mainstream gamers is more important at this phase. They are the ones who do live streams, posts in gaming channels etc. And so far a lot of people are coming for alpha requests in discord and Telegram. Personally I think we as players and investors should also help in promoting. For example, I helped arrange this podcast interview of Hash Rush team on Steem, which is a well known platform used by thousands of crypto people and a lot of whales also!!
https://steemit.com/msp-waves/@aggroed/sounds-of-steem-peace-academy-and-minnow-mayor-town-hall-featuring-the-rts-game-creators-of-hash-rush Marketing is always done with the help of users. But of course in this past month, they have improved quite a lot in marketing. And I guess after Beta, things will drastically improve as it has a prize pool of $30K and then in December there is listing of Rush token on a new exchange(s)!
