The competitive 3V3 elimination mode returns this year for a second season which will take place during the Halloween Terror event — released with update 2.76.
You'll have to team up with two other players to eliminate your three opponents in a Bo5. The winning team is the one that reaches three points. How to reach three points? Easy, kill them all — knowing that there is no respawn in this mode.
Once you've won a round, the heroes used are blocked for the rest of the game. Heroes' choices must be strategic and you should not use all your best cards in the first round.
If you play at least 10 matches — finishing off your ranking games — you'll earn a player icon, a tag and competitive points at the end of the season. You will also earn competitive points for each victory, as in all ranked games.
These competitive games count in the 9 victories you've to do for the weekly challenges and the weekly rewards. Don't wait, and get ready for battle!
