GosuGamers have previously written about the prizes, follow this link for information.
Already over 250 teams have signed up, among those are:
DTS.Chatrix, Tribal Gaming, The Elder Gods, Kingsurf, PMS.Asterisk*, Ducky's Dream Team, Storm Games Clan, MCiTY, Nirvana.int, Os|One and Competo.
Hostbots will be provided, making sure matches will run smoother and hopefully minimizing the issues of delay and spikes.
Quoting Tournament Supervisor Matthias ‘Losemann’ Beyer:
"We are happy to welcome a good mix of amateur and professional teams, which are spread all around the world. Additionally to the regional seeding, host bots are giving us the opportunity to have a successful and fair tournament with great games and awesome broadcasts. I am looking forward to some exciting and fun matches."
